I have a 3.6" pulley, it made 13.5 lbs of boost before even getting to high rpm, it was overloading MAF sensor, so i have a 3.8" coming today to lower the boost im only on 91 octane , completely stock other than the si trim

Bad tune or ....? What happened? I see that many are running a 3.4" on a t-trim w/o issues.....? You do lots of drag racing?
