Audi RS4

We've been programming these cars since 2006, when we originally tested the car back then we got around 26hp. When we programme these cars we can raise the RPM but not by much, 150 is the max... anymore will damage the engine. We also remove the speed limiter, turn the volume up on the exhaust in 2nd/3rd gear, advance the timing in the mid range/top end, etc. I went back home a couple of months ago to London and we decided to play around with the RS4 again, a friend of mine mentioned a modification that can be done to the air box but we never had a chance to test it until now and it worked... you can gain an additional 20Nm by performing this mod to the box.

Alot of owners complain about the shifting on these cars, this problem is fixed once the car has been programmed.

This car also has a Milltek exhaust and K&N air filter.
