downhill32 Posted April 25, 2008 Share Posted April 25, 2008 hay all, my problem is i recently installed a boost controller and wound my turbo(stock) to 12.5psi.now when full boost hits somewhere between 4500-5000rpm the exhaust starts to make a poping sound and the car starts to miss fire(wont pull anymore).my car is a r32 gtst with a full exhaust,fmic,chipped ecu,pod filter.my thoughts are that it could be one of 4 things the coil packs which i checked today seem ok,the spark plugs, or that the injectors or fuel pump is maxing out, any help would be great. thanks Link to comment https://www.sau.com.au/forums/topic/216410-need-help/ Share on other sites More sharing options...
The Mafia Posted April 25, 2008 Share Posted April 25, 2008 you've solved your own problem - I bet your plug gaps are not 0.8mm Link to comment https://www.sau.com.au/forums/topic/216410-need-help/#findComment-3822539 Share on other sites More sharing options...

Roy Posted April 26, 2008 Share Posted April 26, 2008 An R32 GTSt with a good exhaust, intercooler and air filter will basically make 12psi without a boost controller. Was that eh case? If not then you could have another problem Link to comment https://www.sau.com.au/forums/topic/216410-need-help/#findComment-3824016 Share on other sites More sharing options...
