Hey guys,
Just got my hands of a slighyly modified gtst r33 as far as i know the only mods are slightly bigger turbo, turbo back trust exhaust, slightly bigger intercooler so anyway ... today i connected a boost guage to check what its actually doing. It reads that it is running 7 psi till about 4500rpm then it hits 9psi. So i went and bought a manaul boost controller just a little t piece bastard and fitted it in.. I set it a turn and went for a drive i hoped that this would make it hold a consistent boost pressure i was on 9psi untill about 4500rpm again this time the bastard jumped to 16psi so i backed off went home and set the controller to as low as it goes so its running standard pressure again. Anyone know why its doing this?
Regards,
Dan
