i have ITR cams...he did dial out overlap but my car actually lost a lil power (like 1-2hp)...so he put it back. yea it dies off...up in the 8500 range...somethin like that...they do charge 185 per hour, it's expensive but get it done once and right, i was detonating like nuts before, i just want my car running safely.. a/f ratio was around 12s...safe...not the most power i could get but i'm more concerned bout safety . i dont have slips yet hope to hit the track soon...big diff...versus stock vs sc even when i had 6 psi...instant torque...yea i'm happy ...for now
