APR stage 2+ 3.0t

[A6sport]

So does stage 2+ mean duel pulleys or UC? Seems UC Should be stage 3?

Got the crank pulley installed today and with the needed flash, I got the latest software installed... My car is pretty pretty quick. Not brute power, just this elegant quickness. and the RS airbox allows for more sound from the SC as well as the exhaust. Fred Astaire, not MC Hammer.

Don't think I'll do the UC, I just don't think the gains are worth the cost. Additionally, I just don't think the motor has that much more to give... All, in all, happy camper.

I've been putting off the crank pulley for months I love to hear feedback like this maybe I'll get one for Christmas lol!

Oh, I want to add this: drove an S7 yesterday, have not in a couple of years, it's not a night and day difference from a tuned 3.0l. IMHO. Very similar, the 3.0l seems more refined. Don't get me wrong, I love Audi V8s, but the S7 seems more like MB, the 3.0l seems more like "Audi" proving that less is just as much more?

Did you install the Stage 2 straight or did you have the Stage I before? I am on Stage I but I find hard to justify the $800 for the stage II when the APR website only shows like 15-20hp. People swear up and down that the Stage II is what you can feel the most but I am always very analytical when it comes to compare the data and I just don't see it.

I would have to find the 3 following proof in order for me to jump to Stage II:

1) I would like to see a car tested at the dragstrip before and after Stage II
2) Watching a video of a A6 or A7 3.0 accelerating from a roll. One having stage I and the other Stage II
3) Watch some dynos showing the gains.

I mean, that is what I have been doing over the years on a half dozen forums when I did my mods on various cars. Dynos, dragstrips, etc.

Ya my dual pulley S4 was as fast as my stock S6, and when I was running full e85 the S4 would have been quicker. The 3.0T is a pretty damn good motor, but limited by the s/c and IATs from the small intercoolers. At this point the platform is maxed, unless someone comes up with a turbo swap, which is big $ and who knows if the motor internals can handle it. It think the UC is not worth the price of entry from what I have seen btw.
I will say however that coming from an S4 to S6, there is a big difference regarding the driving characteristics of each car.

Did you install the crank yourself? Which brand of crank did you ultimately decided to go with?

Do you feel most of the gain in the low end of the tach?

Snout pulley is worth it

Just had stage 2 with the dual pulleys installed on mine. Felt stage 1 was a bit peaky in power delivery. Stage 2 is very smooth and comes on strong at lower rpm. At first I thought I had made a mistake going stage 2 until I looked at my speed while passing another vehicle. (Fortunately no caught me, as I would probably be without a license) Jumping on it earlier today, could have sworn I heard all four tires chirp when taking off. Then it could be my imagination playing tricks too.

Do you have pics of your intake install? Interested in plumbing configuration that you settled on.

Funny I am not tuned but have been wanting to do it, just not sure how stable the stage 2 would be on stock internals. I don't want to do stage 1 then stage 2, might as well go all in and do the stage 2, I want ecu, tcu and both pulleys at the same time, if it's not going to compromise motor. I know nothing is guaranteed and it's all aftermarket, just want to make sure first.

I did just install and IE intake and I hear the SC more but my exhaust seems quieter in the low rpm vs stock. If I jump on it, it still has that bad ass tone my AWE track exhaust has.

That being said, has anyone used VF engineering? I can get a pretty decent price via a friend of friend deal. But no one has much info and I haven't been able to over to see them in person.

Can I get a little clarification? I can't find straight answer. When going Stage 2, all you need to do it is replace one pulley? I was under impression that a new downpipes are needed too? Is it not needed in this case because A6sport already had S sport exhaust installed? Would stock exhaust cause damage cats and/or o2 sensors?
I have stock 2014 A7 and I'm considering going straight to Stage 2 but I want to keep this car for a few years as my daily driver, so reliability is important to me. Is one pulley in this case better than dual? Will I run into cooling issues with dual pulley setup?

[FastLane1000]

You can run stock exhaust and no cooling upgrades just fine on an A6/A7 with Stage 2 tune and pulley and maintain excellent reliability. You only need to replace the Supercharger pulley for most Stage 2 tunes. The crank pulley is optional and would require a specific tune from most companies although I do believe APRs latest Stage 2 covers single and dual pulley setups.

Here is my take on things. I have a 2012 A6 3.0T. I have been running the Unitronic Stage 2 SC pulley and tune for about 20,000 miles. I now have 78k on the car. It drives like it came from the factory this way. Much better mid range and top end, still Audi smooth. The jump from stock to Stage 2 is remarkable. I have no experience with a Stage 1 tune. Fortunately our transmissions are rated for 550 ft/lbs of torque. The fuel systems seems to be sufficient as well from what I have read. I am interested in hearing when fuel system upgrades are needed. Where you might run into problems is back to back full throttle runs. The IATs will rise after consecutive runs so the power may not be repeatable in all climates. For someone living in Chicago you may have less problems than say someone in Miami. I did hear straight from Unitronic that they have a crank pulley and dual pulley tune aimed for Spring of '18. They do not seem concerned with a cooling system upgrade but again they are in Canada. I have looked into the APR UC but the expense to switch is absurd. You can't just buy the UC and tune for a reasonable price. You have to buy their stage 1 along the way which is BS in my opinion. This brings the cost to roughly $3,000 for a tune and throttle body. If you look at the Dyno graphs on APRs website you will see how the CPS allows the car to make back to back runs while keeping IATs manageable. I would love to have the APR UC and CPS but if I read it right, you are looking at $4,000 for a throttle body, radiator, necessary hardware, and tune. What is looking more feasible for Me is UNIs crank pulley and tune and then possbily the APR CPS eventually. That should bring my cost to about $1,500. If I was doing back to back runs at the drag strip or lived in South Florida I think the CPS would be needed ASAP. For a daily driver maybe not so much. I would love for APR to chime in and maybe offer a switch program. I would think they could benefit from the increased market share and sell a lot more of the supporting hardware.

Just one pulley, downpipe stage 2 is for 4.0TT.
Stage 1 = tune only
Stage 2 = pulley
Stage 2+ = Dual pulley or UC (really this should be called stage 3), but there was a stage 3 system before by APR which is supercharger swap, that thing isn’t dead.

[A6sport]

I did stage 1, then moved to 2, and now dual pulley + RS7 intake.

I did not do it a local tuning shop handled it for me. I went with APR since I have their tune and SC pulley.

[A6sport]

It was plug n' play, no plumbing modifications at all. I used the all of my stock 3.0l hoses and the RS box. super easy. (except for attaching the secondary air pump hose on the bottom of the box. you have to kinda be an contortionist to get it connected.

How is improvement from Stage 2 to dual pulley?

can't say definitively, yet, but I like the sauce...

[AUDIofil]

Thank you guys for clarification. I think I'm gonna go with APR dual pulley tune. I'm not going to run drag races or anything like that, just occasional spirited acceleration to boost my mood:)
I might do RS7 air box swap purely for SC sound upgrade later on.
A6sport, if you don't mind me asking, how much was labor cost on crank pulley install?

I agree, elegant quickness is the result, did the same with my 2016 A6. The eight speed transmission does not like to be hammered, It prefers a smoother acceleration. Cannot imagine needing any more power for daily driving, nothing short of astonishing. Had to wait two years for the product to become available. Other car is a Porsche 991, Audi is every bit as fast at this point, although 991 does handle better

[Dhayward84]

Glad this thread came up. I’m currently on the chipwerk setup with my car and can’t decide what route to go for tunes. I think I’m going to max out at stage 2 and then upgrade the cooling at some point.

I’m just unsure what company to go with for my tune. I️ would like to hold out for a tcu tune also and I’ve seen apr hint at it but I would rather support epl or something as their prices are better.

If I were to start over I would go with APR. They are doing the most R&D and offer the most upgrades. They should be launching their TCU tune for the 8 speed soon. They are the only ones to offer a complete throttle body upgrade with the Ultracharger. You definitely pay for the R&D though and you have to use an APR dealer to install their tunes.

Here’s my review of the UC if you’re still thinking about it.

I would wait and see if the TCU tune helps, but not worth it right now IMO.
