I was consistently getting 4.3 with stage 1 and now get 4.2 with stage 2. Sport+, lift off the brake and hammer the gas. Standing on the brakes and getting the revs up slowed things down considerable. I have not raced a B7, but I slowly walk away from new M3's. Oh, they get so pissed. The best part is at the next light when they ask what the hell I have done, I say "Nothing, it's stock".
