I'm a big APR fan myself. If anyone is interested in purchasing an APR tune in the near future for their S4, please PM me for a great deal on a $1,000 ECU upgrade gift certificate! Easy savings for that expensive 3.0T tune.
I have a 2012 audi S4. I have been getting mixed info from Audi, other owners, etc on which is the better mod to go with to boost engine performance. Anybody have info or experience?
We have a full catalog of performance items for the S4. We have software with program switching, a pulley upgrade, intake upgrade, exhaust upgrade, and full cooling system upgrade. We are also in development of a full stage 3 supercharger system!
