My cousin and i raced a few times today on our way out to bimmerfest. His car is a N55 DCT 135i with Proceed rev2, BMS catless DP and magnaflow exhaust. We stopped at the gas station and did 4 gallong E85 and pump. My car is a 2011 DC M3 with Proceed and PWM meth, high flow cats and magnaflow exhaust. My car made 400whp and he pulled me by a car from 60-130. I was shocked how much faster his car was with the E85. All we did is put it on map2 and set it to aggressive.
After the first run, he heat soaked and i pulled him every other time. But still, These N55's are not to shabby.
