Hi i have a 02 wrx but when im racing sometimes it happen at around 80 or 100 my car will literally jerk like a stall out or something? could the wastegate be the problem? i am pushing high boost or what could be the problem. I have all supporting mods for what im about to do to it, 720cc injectors, hks bov, 20g turbo, apexi full exhaust up and down pipe + performance cat, stage 4 clutch, walbro fuel pump, forged rods and pistons. But before I install all that i wanna know what the problem could be please help I am new to the forum and i hope people are mature on here and dont act like the kids on xceedspeed. Could it be my wastegate im pushin 21 psi so im thinkin about gettn a turbo internal wastegate for a 20g. But that still doesnt solve my problem, i have a high stakes race in a few days so i need help asap. Thanks guys... oh p.s. i just read that fuel cut could be the problem if so what should i do about this, will the walbro fix that if installed?
