My car was stage 3 car with t34.48 on greens.
I replaced with TT T35.55, Ab07, light blues, head ports mildly worked, AS inlet manifold, similar boost as before with 21psi held. The combination of changes has freed the top end up considerably making 360bhp at MSD late last year. How much of that is down to the Cam I don't know but with the other parts as well it drives well. It likes to hold onto revs more now rather than feeling a bit breathless at the top end. I wanted it to idle and run like a sewing machine and the AB07 is so mild it fits that bill perfectly.
