Well im not sure what to think, after reading this thread i don't feel to bad since its my first launch log.
I launched in M1 doing a brake boost for 2-3 sec(too long?)
took it to redline into 2nd
E90 has Cobb 4.01 Aggressive stock throttle map with an AFE DCI
car does have 41k on it
going to try it again tomorrow in DS and BB for 1-2 sec
