Just installed APR Stage 1 on 2012 A7 3.0T

[bthomas22]

I just got the APR stage 1 installed today and had a few questions:

- Throttle response at lower RPM's seems more sluggish than stock - especially in sport mode
- Is there still a change in shifting in Sport mode with the flash - (was a huge difference stock)
- APR shop told me it did not need a break in period for the ECU to adapt to flash - is this true?

I have not had a chance to open it up yet, but as mentioned earlier, it does seem more sluggish in lower RPM's. Has anyone else experienced this?

Do you guys have any advice as to what to expect?

Thank you! Hopefully I just need a few more days of driving for the ECU to adapt.

Give it time to adapt then you'll see some big changes.

I had this a6 3.0 TFSI for 3 years, throttle lag was the reason why i sold it.

Please keep us posted.. hopefully just time needed to re-adapt, assuming it had adapted previously to a spirited driving style.
Do you feel any positive difference otherwise or negligible under lower RPM driving. Maybe you need stage 2 to feel any difference around town.

Thanks, guys. I'll post an update after my drive home today. There are some good open stretches on my commute.

I will note that the throttle response at lower RPM's seemed better prior to the tune. I do have an aggressive driving style and always drive in sport mode.

...- APR shop told me it did not need a break in period for the ECU to adapt to flash - is this true?...

No, that's not true - the APR dealer mis-informed you.

Give it a few days, not just a couple of hours - the ECU will figure out what's going on and THEN you'll be like - WOW!

[bthomas22]

Glad to hear that zcd2.7t!

I recently installed an intake on my 3.0t and the first thing I noticed was that the lower rpm was really slow too. It's been a few days and now it's much more responsive. Sounds like it may apply to the tune as well. Let us know your thoughts and impression

Give it a day or two to adapt. I went from chipwerke to stage 1 and was really sad as I drove home from the shop. Thought it was a huge waste of money as the chipwerke felt way better. But by the next day, no regrets. Same or more power as the CW but much smoother. Just wait. Also get an intake if you don't have one already.

Oh and get stage 2 already...oh and an overdrive pulley....ok I'm done.

Glad to hear that ntsantos. I took it out tonight and I did notice a lot more power in the higher bands of RPM's, but I still noticed it was still sluggish on the lower end. It is shifting through gears at a much lower point in sport mode at lower speeds and I believe that's what is causing the feeling of decreased power and throttle response. Did you have the same experience with throttle response and was this corrected?

Also, I just ordered a Roc Euro intake and should have it next week! Did you notice any improvement with your intake and did you get a new exhaust system when you did the intake? I've heard that it is best to get a new exhaust system along with an intake to balance out airflow. Any thoughts? Thank you all for your input!

I will continue to post updates over the next few days.

Throttle response improved a little bit over time as I remember. I only had stage 1 for two weeks before I went stage 2. Even the first few hours after stage 2 had me pissed off. But after a couple long drives I was happy again.
I installed an Injen intake after stage 2, and that made a huge difference.
I had my exhaust installed after another 2 months which really opened up the midrange to top end. It did make the low end less snappy. I think others may have experience this too.
So after the OD crank pulley, the low end snap is back plus more power throughout.


Edit - honestly, unless you're after your car sounding more aggressive, exhaust would be the last upgrade if I had to do it over again.

It varies a bit car to car.

During a flash, all the stored values for the car are reset. If your local fuel or atmospheric conditions require decent amounts of correction, the car will take a bit to re-adapt and not run as well until that happens.

Georgia has similar fuel to Alabama (some good and some really bad, almost all with 10% ethanol) and high humidity. I could see it taking 5 or so drive cycles (20-30 minutes each at varying speeds) to get back to where it needs to be.

Thanks, Sean. It is already starting to change A LOT. The increase in power is definitely apparent now and the low end torque is coming back.

Thanks for the input, ntsantos. Can you elaborate on the OD pulley? I thought that was included in Stage 2 upgrade, but sounds like i'm wrong

Great advice on the exhaust system...I'll hold off on that until I get some more upgrades.

Stage 2 is supercharge pulley, many S4 owner also installed OD pulley to get a little more power out of it, but ntsantos is the first one I heaed did that on C7

Just search "Dual pulley" on the B8 S4 forum and you'll find some great info on adding an OD pulley.
