many thanks to Evolve, I finally can enjoy driving my m3.
My car has K&N filter and a full Akraprovic evo exhaust, i first installed Tectech stage 2 . The car had little gain, huge flat spot and pull backs between 1.5k-2krpm. There were no support provided by Tectech to resolve this issue.
Today, finally I got my evolve stage 2 with overrun. We have it flash into the car and transformation is amazing, exhaust sounds deeper (very nice) and the car pulls smooth throughout the rpm. The car now has great mid range and very strong top end, pulls much much better then the
Can't wait for my DCT cable to arrive for DCT upgrade and maybe cat-less for some flame throwing fun with the overrun.
Many thanks Evolve.
