B8/8.5 A4 Tuning Options Megathread

[tominabox1]

The purpose of this post is to catalog all of the available tuning options for our B8/8.5 Audi A4s and compare their advertised statistics. I will try to tailor the results for 91 or 93 octane gas and make notes where higher octane tunes are available but their claimed gains will not be included for comparison. Please let me know if there are additional tunes I’m unaware of that should be included!

GIAC Stage 1 Plus: +39HP; +~60 Ft-lbs.



GIAC no longer seems to advertise their “Stage 2” tune. Previously it was said that the addition of a HFC made the Stage 1 Plus tune a Stage 2 tune. Now their website states that bolt ons will improve performance.

Ah thanks I had looked them up earlier but forgot to add it to your list.

Nice work. Hopefully this is referenced often moving forward in regard to "I want to tune my car, whats the power" type posts.

They do full range custom dyno tuning all the way up to big turbo tuning

Anyone have experience with UM's custom tuning? I have an independent company wanting me to be a guinea pig to a drop in turbo bigger than a K04.

Also I’m tuned by UM with the stock turbo and I’m seeing boost around 22-24psi (which is higher than the chart on their website) so idk if it got revisioned or something but it makes me curious

I have unitronic stage 2 and eBay downpipe on my 2010 Audi A4 Quattro. I ran 14.08 at 98mph quarter mile (uncorrected) which at 3890lbs fully loaded with driver correlates to 280horsepower vs 211 stock. So increase of 69HP which is more than advertised.
You really have to go with quarter mile times to make it fair as dynos are all variable. I mean tracks are variable as well but you can't cheat a time slip from a regulated track. If I took the spare tire and floor mats and such out the time would be lower but weight lower as well, so horsepower calc would come out the same.

Id like to see a list of quarter mile times by tune.

Heres a calculator: https://www.calculator.net/engine-ho...=et&x=0&y=0#et

I believe JB4 is jumping in the B8 market. Thinking of stacking it on my APR 2 for a little extra tweaking and water/meth will be able to be controlled by the JB4 as well.

Also HPtuners is up and running on the B8 with some pioneers making some headway.

Burger Tuning's JB4 is currently in Beta for the B8 and not available for retail at the moment. As far as I know I'm currently the only one running it on the platform

What would y’all recommend for a stage 2 91 octane tune? I saw apr makes a little more power than ie, but I’d like to be able to flash from home. Open to other options too, thanks.

I have APR now but if I had to do it over again, I would prob go with IE. HP wise it makes slightly less but their tunes make more torque. Also I hear their customer service is on point.

[SNice]

I’m also only interested in ‘tune at home’ options. I’m hearing and seeing a lot of good things about IE. Does anyone have any experience with GIAC?

I heard that they have good customer service too, but reached out by email, Instagram dm and on Audizine and haven’t gotten a response yet:(

I went straight into the stage 2 with IE, and I’ve not had any problems. I have all the required and recommended hardware, minus the exhaust. I’ve been extremely happy with the results. My only gripe is the fact I bought the tune a week before their “tax sale’’ and they couldn’t have gave me the heads up? Upon looking into the return policy, they said there would be a 10% restocking fee if returned. Mainly the cable I suppose, but not worth the extra 5% discount in the end, if I were to actually go through all the trouble. Long story long, I like the tune, and the company seems pretty easy to deal with.

Another problem is as soon as I felt the increase in power, I felt the want to spend monies on the K04 for MORE POWER!

[J.kaseno]

I've been looking into available tunes. Thank you for compiling this information for easy comparison! One question, I've searched and found mixed answers to. I plan to have all other supporting hardware, but how would heat soak adversely affect numbers with stock intercooler? I've also considered upgrading to the 3.0tdi intercooler as its budget friendly. Trying to bring out the fun factor of this car, without upsetting the girlfriend too much.. at least at once. Just got to let her down easy😂

[J.kaseno]

Thought I included it in my post but I was leaning towards the IE Stage 2 tune to be more specific.

I have the IE stage 2 tune and I love it. Good gas mileage if you can keep your foot off of the pedal. I am also running their crackle file with it and tunnels are so much more fun now.

Are all the +hp and +torque values from the crank, or brake hp/tq? Would be good to say, one way or another. I can see certain vendors *cough* giving values at the crank to look superior, while others giving brake-values because they're bros.

[Chatchie]

Get the tune that your local shop does or get one that you can tune from home like IE or UNI. If you have a flex fuel car APR is what you want for thier e85 auto tune.

They're all close in numbers untill you get to e85.

Yeah this is the only thing that makes me sad about the IE tunes right now. The lack of the E85 tune. But they keep promising one here in the future. Fingers crossed 🤞

I’m running the Unitronic Stage 2 tune on my 2015 A4 P+ 6MT with test pipe and intercooler. My local shop partners with them and did a great job on the install. I’ve been extremely happy with the upgrade and the only issue I had was my intake manifold had to be replaced. Honestly, I think it was shot before the tune but I never realized how bad my low end torque was. For some reason the tune triggered the CEL for the IM and now that it’s been replaced I can tell it was not operating correctly for a long time. I always noticed the car would bog down when taking off at a light or stop sign. Side note: if you want to be able to do the tune yourself the Unitronic apparently offers the cable to do it. PLUS if you’re going K04 then Unitronic offers a BW kit and you can go stage 2+ BUT they’re out of stock and I can’t get a definite answer on when they’ll be back. Hope this helps as very few people mention Unitronic here.

Being that where I live has emissions testing every 2-years, what are the best options that would allow me to pass emissions? Can you simply go Stage 2, then backflash a month before emissions testing to let it run through the cycle, or would I be stuck with Stage 1 only?

What is the nature of you emissions testing? Just an OBD check + visual inspection or do they put a sniffer in the tail pipe?

Where I live it's just OBD+visual and you are permitted to have one of the O2 sensors read "not ready". As such, one could run stage 2 with a high flow or gutted cat and pass inspection. If your state's emissions inspection is similar then you are set.

Otherwise just stick with stage 1. If you tried going stage two and back flashing to stage 1 before inspection, you would also have to go back to the stock cat which would be a hassle. Stage 1 with a high flow cat or test pipe with throw a check engine light as it reactivates the secondary O2 sensor.

Recently acquired a B8.5 and was excited to see this Megathread...was expecting more info/posts tbh.
APR is currently the only OTS tuning company that offers FlexFuel tunes correct?
Also, is this not supposed to be a sticky?

[cybernet99]

Another tuner that is doing custom remote tunes is Frank Mabo. He uses Eurodyne under the covers, but is actively supporting our platform. If you are curious about what it is he is offering, check out his site www.mabotech.net he also sells some of the harder to find components that are not mainstream like higher flowing direct injectors to replace the factory injectors. If the car is straight forward, probably one of the OTS tunes are more than good enough for most, but for the people who are running bigger turbo's etc, he is very active and excellent customer service. Also has a very active private FB group.

[dalmation53]

Damn seems like APR has the more hp and torque numbers out of all of them.

Looks like once lockdown is over, possibly by end of month from what I hear

[Ark88]

If one goes about getting the APR e85 tune does that limit you to running only e85 fuel? What about if you use 93 octane on an e85 tune.

[sciroccokid]

If you have an allroad then e85 is baked into every tune (91/93/etc). It's flex fuel just pull up to pump and pick the yellow hose. Mix of gas to e85 doesn't matter, ecu does the math. Nothing more to it.

[HOJeepster]

I have e85 allroad - but I don't think your statement is true. If you run an APR tune, then you can run e85. However, from what I've read if you run IE Stage 1 you can't run e85 any longer since the tune doesn't account for ethanol content.

I have apr and can't speak for other tunes. I believe you are correct from what I've read on the forums.
