IE Performance ECU Tunes For Audi B9/B9.5 2.9T RS5 & RS4

B9.5 Audi RS5

Great tune and very straightforward install! The car is already pretty quick, but this really takes it up a notch with doing a major car overhaul. Unfortunately, my build year hasn’t had the TCU unlocked by IE…yet, but can’t wait for that to become an option.

Wish the crackles were a little toned down...5 seconds of crackles after letting of the throttle seems a bit much

The Trueflex system is amazing, super sad the stage 2 TCU tune does not work in my 2021 RS5, But seems to be working great with my 034 stage 2 TCU tune. really wanted the rolling anti lag.

Car is a whole new monster

Install couldn’t have been easier other than a small communication issue between dongle and phone. Just had to reconnect the dongle and open the app again. Didn’t take hardly anytime at all to do the flash, ECU, and TCU tune. MAYBE :30-:45 total.
