overboosting
i have a 91 turbo supra (automatic transmission ),i need some advice.. my car is drivable, but when i hit the gas to pass someone or just because, the boost needle goes up to 15 psi (more less) on my aftermarket meter and the stock goes all the way to the top,, after that is total downhill cause the check engine light comes on (for a second or so) and i start to worry cause i dont want another bhg,, i think im experiencing fuel cut?.. what could be the reason for that boost pressure? i dont have any mods, only hks mushroom filter and hks ssqv bov and my exhaust has no catz just a muffler with a 4 inch tip. I want stock boost not this crazy thing,, could it be that my boost pressure sensor has gone bad? or my wastegate actuator? or the timing is off??... when idling it doesnt shake or knock nothing like that, the idle is perfect it sounds clean and deep... ANY ADVICE?
