Keep it, it's fine. I'm running the ACT Street lite flywheel on my boosted ITR and haven't had any problems. Putting down 289whp @ 7psi driven daily. I'm also running the ACT Heavy Duty Street/Strip clutch without any problems. I know somebody else who has the Pro lite on his 265whp GSR and can't speak highly enough of it. Some might have problems but I havent.
