Poll, which tune and why?

[Nsd991]

2021 RS6 finally ready for a stage 1 ish tune and intake. Only a year left on factory and have decided to keep this car as I can’t think of a replacement daily driver that will check all the boxes of this car. I’ve scoured through the various threads on this site and I don’t know which direction to go with. Ideally I’d like to get a tune and intake from the same company. So far I’ve added that Akropovic exhaust and have the rs6 performance wheels en route. Not planning on upgrading beyond stage 1.

I’m considering 3 brands and will briefly list the cost and my pros and cons of each:

IE
Tune
Cost $1499, power link $179
Power stage 1 93 octane 690hp 780 ft/lbs torque
Intake
Cost $1999
Optional turbo inlet pipes $399 (other 2 options have these included, but these look metal not plastic, APR is metal)
Pros: install and uninstall or upgrade via phone app (nice user interface with additional diagnostics), also has transmission tune included, Stop/start de activation
Cons: price compared to APR ($4076.00)


APR:
Tune
Cost $995.95, mobile tuning $149.95
Power stage 1 93 octane 710hp 751ft/lbs torque
Intake
Cost $1537 with turbo inlet pipes
Pros: 30 day money back guarantee, cheapest
Cons: giant Apr logo on intake and it doesn’t have the front section where hood latch is in carbon ($2682.95)

Unitronic:
Tune
Cost $1530 (sale till 2/24/24) Uniconnect cable $164
Power stage 1+ 93 octane 753hp 709 ft/lbs torque
Intake
Cost $2999 with plastic turbo inlet pipes available in multiple finishes
Pros: can flash from home
Cons: most expensive of all ($4529.00)

Eventuri intake
Cost $2995

Any feedback from others would be appreciated.

I've owned going on 20 different Audi's since 2013 and tuned literally all of them except when I own one before a tune is available. I've run 034, EPL (RIP), APR, and Uni and they're all pretty consistent across the board for a given octane level (because there's only so much to work with) regardless of what a dyno says.

I have a '23 SQ that's 034 91 stage 2 for the lil lady's car that she loves and is doing beautifully. I literally just tried to add IE to the mix for my newused '21 RS6 because of flash at home ability and that went less than smoothly. They sent me a bad cable (whatevs, happens) and the support and trying to exchange process was a shit show so I sent it back for a refund, of all of the vendors I've had an issue across, they handled it the worst, so take that for whatever it's worth.

Ended up going w/ APR 91 stage 1 (was at my local shop same day and flashed in under 30 mins) and it's absolutely everything the car was missing stock; feels 10.8-11.0 @ 125-126 territory based on what my M5's ran and what every other tuned or stock (including my C8 RS7 that did an 11.47 @ 119 bone stock) high powered vehicle I've had has run. If you only did one mod to your C8, a 91 octane tune from any vendor would be enough. I can say that APR's tune adds the missing instant down low torque and part-throttle response and the first time you get a totally empty on ramp and freeway ahead of you, it's laughably (in a good smiley way) quicker than stock and does that thing my M5 Comp's did where they keep pulling harder in every gear.

For only stage 1 on pump gas you won't be upset with a tune from any vendor, so I'd go with best bang for the buck!

Thank you for the detailed response. I do have an Apr vendor here locally so that’s a plus. Did you do an intake?

[HurrayFive]

For sure, aside from the Vossen HF5's I have arriving next week and deleting the exhaust resonators with straight pipes for a little more volume I only planned on the 91 tune as far as mods for this one, so no plans for an intake. I've mix and matched vendor mods and tunes across every other vehicle though, and an intake will work all the same with any of them if you've already got one.

EDIT: have since snagged an APR intake (that I found in stock) because I can't help myself, little moar loud, wee tiny moar pep on top of tune

Based on what you’ve said I’m starting to wonder if an intake is necessary…..

Yeah, if you're chasing stage 2 and beyond powah an intake becomes a requirement on this platform and they do add another ~4-5% to stage 1 but for most people you're not going to need anything beyond what a stage 1 tune can do by itself on this car, even 91 feels high 10's. The Burger Motorsports (JB4) intakes are also the only open element setup that still adds power via their bigger turbo inlets but will add a lot of induction sound (and is one of the cheapest options), if you get bored with the sound. I may go that route just for a bit more volume if the resonator deletes aren't enough alone. Feels like I could crack off a 10.9 on a cool & dry morning once my new wheels & tires get here with only the 91 tune tho, will give it a go!

[Nsd991]

Great I have the performance wheels coming and may just add the tune for now to not making it glaringly obvious (with added intake) when I take the car for service. So far I’m leaning towards IE intake if/when it happens. Some good videos on YouTube..
Like you say they are all similar so if a good deal pops up on any intake I may just do it.

What happened to EPL? I used to run their SQ5 tunes. They were great to work with

[HurrayFive]

They dipped out a couple of years ago now in a kind of not-so-professional way of posting on FB and the forums that you had basically a year and a half of them keeping their server up for you to be able to flash back to stock but no other updates or sales were going to be offered. I think Chris just got tired of the job and wanted to be done, their software (and Chris' ultra-responsiveness) was the best though. Always reasonably priced, more features than other tuners or had them first, and they gave you a big discount if you had purchased on previous cars. Wish they were still around, I preferred their throttle response and transmission tuning to any of the current vendors.

[Nsd991]

Do any of these tunes enhance the pops and burbles of the exhaust? I think I read somewhere that one of these tunes eliminated the stop/start feature???

034 (does) and EPL (did), 034 isn't quite out for this platform yet but it's coming real quick. It does a heck of a job on the S models for both of those things, including my current SQ. I think IE's offers pops and bangs. APR offers neither, wah wah. I had to snag some 034 mids and APR's intake just for a liiittle bit more volume on what's otherwise an excellent tune of theirs, car is just a tiny bit too quiet in the cabin on stock hardware.

[nate1031]

IE advertises enhanced burbles. As dumb as it is, it made me really lean their way. I love me some burbles. Lately I've been leaning Unitronic since most people are running their tune and seemingly no issues. Reliability is primary concern for me. I'm still on the fence, like you. I've been going back and forth for quite sometime now. FWIW, I did get IE's intake installed (still without inlets because I have a '23) and my wife and I both noticed that it has more low-end responsiveness. We even noticed a slight increase in exhaust sound too. My son (super into cars) says he it's definitely louder. I too did a full (3) res delete.

[Ace22]

I went with Unitronic mainly for the tune at home and reliability. APR was pulling some “our tune is a gazillion dollars” crap at first, then magically it was competitive after people complained. IE was not in the game yet when I chose to tune.

[Daytona RS5]

Any feedback on the fact that integrated engineering combines a transmission tune with theirs? To me that's kind of a big deal and they seem to be the only one that is offering that as far as I can tell.

They mentioned the new SQ7/8 is at the top of their list and they don't support any of the 4.0 TTV8's yet. That tune is usually the same across SQ7/8 & RS6/7 as it's literally an 95% RS6 engine w/ RS6 turbos just factory detuned to 500HP (is why I was going to get a new face lift '24 SQ8 but they're just a little too portly and I prefer the RS6 overall) so when tuned they make the same power on stage 1.

Basically if they support the SQ7/8 it'll be easy to support the RS6/7. I will switch to 034's tune the moment it comes out as I prefer their linear throttle, flash at home reliability (solid apps), and their true TCU tune mapping whenever they offer one.

Thanks for noticing that, I’ll add it to the summary above. Just to mention, I am now completely confused as to which tune to go with. I don’t necessarily want enhanced burbles. . I do like the ability to flash from home. I’ll have to re-check but I think the unitronic one requires a Windows computer. We are all Macintosh at my house so that might be an issue.

It's not a true TCU tune (they will, like all tuners, definitely charge you for that) that remaps the the shift points in every gear and mode, it's just how some vendors update the TCU to work with the increased torque via a TCU "patch"; it does modify maximum allowed TCU torque to deal with the increase from the ECU tune but that's it. 034 does the same thing for platforms where it doesn't actually support offering true stage 1 and 2 TCU tunes that completely remap the clamping pressure of the ZF, when and how hard it shifts in every gear, throttle tip in, all of that... APR doesn't require a TCU patch for this platform to report correct torque numbers to the transmission, it's just a difference in method.

Nobody offers a "true" stage 1 or 2 full TCU remap (which is an extra $800+ on the B9 S4/5 RS4/5 in addition to the ECU tune cost) but the platform could sure use it, right now only Uni offers a stage 3 TCU for big turbos. It's the one thing the RS5 Competition had going for it over this platform, completely revised TCU software that was ultra aggressive in Sport and befitting an RS model. Hoping 034 releases ECU and full TCU software whenever they make their release, makes a massive difference with a true, full TCU tune that makes the car shift as aggressively as the ZF is capable of as in my M5's and the RS5 Comp.

[Nsd991]

Great information Hurrayfive

[allenyao09]

2024 RS6 Performance has revised TCU software that's more aggressive. Anyways to flash that into the non-performance RS6's?

[JWebb_C7_Comp]

Hey guys,

Thanks for all the great detail.

Am I missing something or is the 91 tune safer/better than 93??

I recently grabbed a 2021 RS7 with 17K miles. Compared to my beloved 2018 A6 Comp (APR Stage 2 (93 octane) with Berk TCU), it's an even more powerful and much louder beast in RS modes, but sublime on the highway. Thus far, I haven't found anything problematic and the car appears to already be APR Tuned with Stage 1 93. Considering intake to allow turbos to operate more freely - not necessarily for the additional power. The comments above make me wonder why some tend toward 91 versus 93 octane. Unless I'm traveling in one nearby state, I can always get 93 octane. And, even where only 91 octane is available, I cheat by adding 2 gallons of e85. Should I revert to the APR 91 tune. It would cost next to nothing whether at home or by the nearest APR dealer, who is about 20-30 min away and had done my wife's Q7 w/o any issues whatsoever.

Also, does anyone do anything specific to oil or cooling to keep these cars in tip to shape?

My past two tuned Audi's ran great w/o additional cooling, but I stumbled across Motul 5w-40 for them and oil temps stayed a bit lower and oil loss was negligible on a 5-6K interval. I dont yet see a Motul VW 511 spec for the 2021 RS7 yet, so I'll stick to dealer juice, which I suspect to be Mobil or Castrol.

Thanks for your thoughts.

[Nsd991]

Update:

I just got APR 93 octane stage 1 tune today! Wow this car is transformed. So glad I put my fears behind me and tuned this thing into a beast. I was able to get an unused Eventuri intake from a friend and will be installing in a couple weeks.

Regarding the 91 vs 93 file, I live in a large metroplex with lots of 93 around, maybe I should have gone 91 and not worry but I think the extra hassle is worth it given the additional gains.

[HurrayFive]

Enjoy the tune!

91/93 is usually within .1-2 tenths difference in a 1/4 mile across all of the platforms I've tested as percentage wise peak power difference isn't huge, if you have pump 93 nearby then run the 93 file. On the west coast 91 is all you've got and in WA where I'm at it's all 92...when I can flash from home like I can w/ 034 on my other car, I'll run the 93 file in our coldest winter months (which logs safely) and then run the 91 file the rest of the year. For APR or if you only have access to 91, run the 91 file. 1-2 gallons of E to 91 (depending on volume of 91 and a handful of non-static parameters) should let you run the 93 file *most* of the time, but only if you log safely. I've only got one E station and it's an hour away so I'm on the file I can run year round out here without worrying about logging.

TLDR; If you're not doing your own logging to make sure fuel trims and ignition advance look safe, run the the file for the octane you have in the tank, 91 for 91, 93 for 93. It's not inherently more safe to run a 91 map with 93 fuel if you have access to 93, run the file for the octane you've got and you'll be fine.

[Nsd991]

Hurrayfive, thanks for the wealth of knowledge. I had the first full day with the tune yesterday and I’m very happy with the results. Maybe it’s just the first day but I couldn’t help driving like a hooligan! I’m sure once I get intake that will only get worse as I’d want to hear the noises. I’m already down to 8-10 mpg so it can’t get much worse :)

[John@DEADBEEF_DynoSp]

We supply a flasher but not the tuning. There are 30 tuners that can offer off the shelf or custom tunes. The flashing is 10 times faster because it uses ethernet, so you don't need a battery tender (my RS6 does a full first flash in 90 seconds, TCU is 20 seconds). We're working on advanced logging which also leverages the speed of ethernet and after that flex fuel. Our price for flashing the ECU is £499 and £199 for TCU, including basic logging. On other platforms, off the shelf tuning files usually start from £100-200, but we are not a one stop shop, there are plenty of those, but you do end up locking yourself to one tuner and old/legacy CAN based hardware. The ECU doesn't even get flashed over CAN any more, time to move on and use the best interfaces on the car.

Worldwide for all MG1CS008 4.0T we can of Audi, Bentley, Lambo and Porsche. There is a free diagnostic tool that has a fault code dictionary for all modules and it will tell you if we can flash your ECU and/or TCU versions.

I've seen you post a few times but this pricing is always confusing, is that the price just to have access to your list of ~30 tuners and then once you've paid for that, you pay whatever the tuner charges for their tune as well but you can flash faster over ethernet?

I also only recognize Silly Rabbit from that list, and I see DME in there and they have had a couple of horror story threads on this forum about not coming through. What are you running personally? There's only a handful in that list that mention 4.0T support and I just don't recognize any of them. Anyone can slap together a tune, being able to flash it more quickly is cool, but it doesn't make the tune any less crap, heh.

[John@DEADBEEF_DynoSp]

We sell a flasher/logger and the price is for that for one car. The content you flash can be DIY or bought from any tuner as we use the same raw binary files that protuners worldwide use with their professional master tools. We just gave them access to a remote market and then made the flasher faster than everything else. It fills a niche and is going well, we are never interested in being just a similar option to everyone else and focus on comms speed and freedom from vendor lock.

Thanks for clarifying, I like the idea as the initial flash time is painfully slow by today's standards (a whole 10 minutes but I've got things to do) when using 034 or EPL's cable or mobile Bluetooth dongles. I just don't know a name in your list well enough to trust (in the US) my engine to! It would be cool if you had a simple rating system on your list of tuners or number of flashes executed via your system for each tuner to get an idea about whose whom.

[John@DEADBEEF_DynoSp]

Most of the tuners are experienced with Motronic but they are not the commonly known international ones in groups because they didn’t have remote options. With us supporting 1400 versions over 7 brands we decided not to offer OTS tunes and make it broader as there was a huge gap for a fast at home flasher for a large range of 4 to 8 cylinder engines, petrol, diesel and hybrid.

Two quick - mostly related questions:

(1) do we need or do we benefit from any additional - cooling
(2) how do you like the Vossen versus HRE wheels? (thinking about a 21" set that would be slightly lighter with MP4S Summer Rubber with a 35 or 40 profile)

My 2021 RS7 appears to be currently Stage 1 APR tuned and runs great. Two older Audi's 2018 A6 s Stage 2 single and my wife's Q7 is Stage 1 software only.

NEED, no, unless you're in a hot climate where it's hot most of the year, I live in the reverse where it's cold half the year and mild the rest. For stage 2 and beyond the factory air to air intercoolers can be replaced w/ much larger units, Wagner offers a kit and I think APR might as well, but that's not a requirement for stage 1 ripping it here and there on pump fuel. These cars aren't weighted for track use no matter what you do to them so if you're really set on HDPE days, intercoolers are worth it. The factory oil system cools down so fast that unless you see it pegging above 230F on a regular basis the way you drive, I wouldn't worry about non-factory oil, trans, or diff cooling. Pay attention to the RS monitor after a couple of hard pulls and everything cools down really quick.

Otherwise this thing logs ultra clean on APR's 91 tune even after a couple of back to back pulls, so I'd more just let your foot do the cool down runs for you and save the money on wheels or something else fun :)

I've pretty much exclusively run HRE flow-formed sets and Vossen's hybrid forged is more or less similar weight and strength for a given size and offset. Not ultralight by any means but a few lbs per corner lighter than the factory 22" wheels and they look great, wheels formed via this process are going to be pretty similar across manufacturers for the price!

I thought about Vossen HF and HRE FF wheels too, but decided on the BC Forged wheels. A bit more expensive than the flow formed wheels but pretty good bang for the buck for custom made forged wheels. 21'' wheels with 295/35/21 tires

NEED, no, unless you're in a hot climate where it's hot most of the year, I live in the reverse where it's cold half the year and mild the rest. For stage 2 and beyond the factory air to air intercoolers can be replaced w/ much larger units, Wagner offers a kit and I think APR might as well, but that's not a requirement for stage 1 ripping it here and there on pump fuel. These cars aren't weighted for track use no matter what you do to them so if you're really set on HDPE days, intercoolers are worth it. The factory oil system cools down so fast that unless you see it pegging above 230F on a regular basis the way you drive, I wouldn't worry about non-factory oil, trans, or diff cooling. Pay attention to the RS monitor after a couple of hard pulls and everything cools down really quick.

Otherwise this thing logs ultra clean on APR's 91 tune even after a couple of back to back pulls, so I'd more just let your foot do the cool down runs for you and save the money on wheels or something else fun :)

I've pretty much exclusively run HRE flow-formed sets and Vossen's hybrid forged is more or less similar weight and strength for a given size and offset. Not ultralight by any means but a few lbs per corner lighter than the factory 22" wheels and they look great, wheels formed via this process are going to be pretty similar across manufacturers for the price!

Thanks for the information!

Oil Temps:

I've got to play with the RS Mode settings and will watch oil temps as the weather warms up. It was about 60* this weekend and I don't recall an oil temp higher than 218* after a long run on on ramp to clear highway. Seems to drop to about 210-212* quickly.

Logs:
I guess I'll find the best method to log this machine and see if timing is pulled, AFRs look off, etc. I haven't really done logging - but for tuning trans - in years as I haven't been pushing the Audi's too hard. Older BMW was another story and I logged it every couple weeks.

I thought about Vossen HF and HRE FF wheels too, but decided on the BC Forged wheels. A bit more expensive than the flow formed wheels but pretty good bang for the buck for custom made forged wheels. 21'' wheels with 295/35/21 tires

What a fantastic wheel; enjoy!

Hey all, new to the forum and looking for tuning info. Like what's posted here, I'm trying to decide between and APR or IE tune. I have a company close by that can do the APR so that's not an issue. I like the fact that with IE you get the auto start/stop switched around, but curious what they mean when they say they've recalibrated boost gauge and display needle glitchyness. Does their change impack the instrument cluster and make it work better?

My 2023 SQ7 has almost 8,000 miles. Wondering how many of you tuned your cars at this point and how it affects service and if anyone has had any issues?

With a 2023 it might be worth finding out if the ECU and/or TCU are flashable. You can plug in with our free software with an ethernet cable that costs from less than a dollar and get a free diagnostic tool. If you then want to flash there are over 30 tuners that can help you.

Enjoy the tune!

91/93 is usually within .1-2 tenths difference in a 1/4 mile across all of the platforms I've tested as percentage wise peak power difference isn't huge, if you have pump 93 nearby then run the 93 file. On the west coast 91 is all you've got and in WA where I'm at it's all 92...when I can flash from home like I can w/ 034 on my other car, I'll run the 93 file in our coldest winter months (which logs safely) and then run the 91 file the rest of the year. For APR or if you only have access to 91, run the 91 file. 1-2 gallons of E to 91 (depending on volume of 91 and a handful of non-static parameters) should let you run the 93 file *most* of the time, but only if you log safely. I've only got one E station and it's an hour away so I'm on the file I can run year round out here without worrying about logging.

TLDR; If you're not doing your own logging to make sure fuel trims and ignition advance look safe, run the the file for the octane you have in the tank, 91 for 91, 93 for 93. It's not inherently more safe to run a 91 map with 93 fuel if you have access to 93, run the file for the octane you've got and you'll be fine.

HurrayFive.. great info! Was reading your stuff and saw your from WA State, I'm in Bothell! I'm assuming your part of Avants? I'm in the process of acquiring an RS6 that comes with a CPO warranty to 100K. I couldn't quite understand APR and their warranty claims? If something were to occur due to the tune.. will Audi most likely cancel the CPO but APR would fix w/ their attached warranty? I could see that being an issue?

Are you still satisfied with APR? Would you consider some of the other vendors? As you mentioned.. 92 is the best we can get out here. I think I would just stay stage 1 but the dealer is gifting me a set of downpipes from another RS6 and I could see that taking me down the rabbit hole.

I too miss Chris and EPL. His response time was incredible.. always answered at all times of the day. Wifes current '18 SQ5 has their tune and its transformed that car w/ zero issues. Was sad to see they are out of the game. Both of my previous S4's were all EPL..
