I just had a FMIC put on and its blowin off pipes, cheap ebay crap! I'm puttin better couplers and t-bolt clamps on in a few days. Anyway i'm having a problem with hesitation through all gears and all rpms. i hope it is due to a leak in the pipes but if not, when i get them fixed and if its still hesitating i am goin to replace to fuel filter. If it still does it after that than i assume its a fuel problem... maybe running rich or lean (<---- any input on this?) I plan on getting a f-con and some 720cc secondaries reguardless if the problem is gone or still does it. If it does still hesitate, will the f-con with stock chip correct the fuel curve for me. I have aftermarket intake, 3" RB exhaust, FMIC, and will then have 720 secondaries.
