Well I've actually got two questions. The first one is, what would be the better performance mod to put on my 2000 v6, shorty headers or a 70mm TB. I've already have a MAC cold air,ASP H.O. pulleys, and a diablo chip comin in this wed. I've also been having some wierd things happenin to my clutch pedal. Normally the pedal comes all the way up like its supposed to but whenever i accelerate quickly and shift quick the pedal only comes up to about an inch higher than the brake. Does anybody know whats happenin and what i could do to fix it?
