Guys, Just over a year ago, I started out modding my A3 with an MTM stage I remap and I was in Audi heaven. Lots of torque with good power up top. Perfect...Until the next mod... Months went by and I started adding things to my A3 almost every month. (an all too familiar story) and I forgot about doing things to the ECU to match the other upgrades (Turbo back exhaust, Air Intake, Turbo Outlet ...) Until my garage (a revo dealer of course) asked me if I was interested in replacing the MTM stage I with a Revo stage II.... Within an hour I had the car back. I didnt look under the hood but I swear they replaced my engine with something else... Changes below 2000RPM is minimal but in gradients where I usually need to downshift from a high gear, it now feels like its a bigger engine with more torque and I can keep my gear. Above 2000RPM, the turbo and the exhaust note feels louder and pulls like MAD. My 6 pot brembo has met its match! Smooth, linear power delivery with even stronger acceleration. I would highly recommend guys who have done the basic remap first (bluefin, MTM Stage I, ... Other stage I remaps) but have added other mods to upgrade their ECU as well. Brings new life to your car!!
