hi i need some help i have a boost problem. i put the gt45 turbos on my car with external westgage 50mil when i run 12 psi makes same powere as when im run 20psi everithing seems to be runig ok dont know what the problem would be? thanx for all the help!!!
Is it tuned for 20psi? Could you be maxing out your injectors? Need more information on what supporting hardware you are running. If your 1/4 mile in your sig is current, then I'm assuming you are running mostly stock gear. Otherwise, start with good ol' boost leak testing.
