hey whats up guys, once again i have ran into another issue. this past weekend i was doing some tuning on my car and i wanted to UP the boost a little bit more, but to my surprise i cant go past 11psi......
i did another boost leak test and my intercooler pipes( inlet to outlet) hold 15psi without trouble and the pressure stays pretty steady....so no mo major leaks there... i got a cheap MBC when the MBC is closed i boost 7spi which is the wastegate spring load MBC half way open = 11psi fully open = 11psi if i remove the boost controller and leave the hose that connects to it by itself, still get 11psi............. so i im assuming i must have a leak somewhere past the throttle body...im not sure how to test the intake manifold and all other vac lines to see if i got a leak there under pressure, because in idling i sprayed starting fluid around injectors, manifold, ects. and idle didnt change. or is it possible that my EGR could be leaking??? any help is appreciated |
