Back again! Now is a question. With the PPE headers, muffler removed also with PPE high flow up pipes and down pipe there is what sounds like a miss at the exhaust tip at idle and a little at say 1000 rpm's? But engine doesn't vibrate at all, and doesn't feel like a miss at all? First thought was a valve needs adjusting but that was done twice before we buttoned it up. Any thoughts? Turbo needs more rpm's to spool up? I am praying not a valve adjustment and we all know why! Has anyone with my engine exhaust setup heard of this? A prominent puff puff vs a smooth flow.
Thanks to all who reply!
