i just got a perrin maual boost controller on my all stock 02 wrx except for bov. and i turned the boost up to 9lbs. good. then to 11 went down to gandy to check it and engine light came on and it seemed like it would bog. is that fuel cut? or what never experienced it. so i drove down to racetrak and twiest down a notch to 10 lbs. ran good then. any 1 kno what i was experienceing? runs good at 10 lbs. engine light still on though. oh yea and i just got a perrin drop in filter upgrade. next best thing to cai i think.
