Ok guys my car has been in shop for almost 2 months.. What original was a tune and adjust timing turned into a 2600$ job... Now I have supertech valves , cometic?? Multi layer head gasket and a few other goodies.. It was dynoed at 364 but the idle is rough and they said its bc of some seals??? In the throttle body?? And they are leaking air which is robbing me of about 50-60Hp.. Has anyone heard of this? Is it coming they say it's robbing me of hp and it's the reason my idle a lil rough
