Hey wats up guys, My buddy has a fully built h22 turbo his car will not boost past 15psi but once his car warms up it drops down to 10 psi and once vtec hits his car bogs down? he has golden eagle sleeve 9:0:1 pistons and his head has stock cams with supertech valve train and dualvalve springs could it be that his valvetrain is to aggressive for his stock cams? so once vtec hits his vtec lobes have a hard time makin it through since he has aggressive dual valve springs?
HELP GUYS !!!!!!!!!!!!!!
