I lost 20rwhp, lost rpms, and basic did not like to function. Cam grinder really feels exhaust is to blame??? Car ran good up to about 5000rpms but then fell on face, I think I may have more compression than before. Higher octane fuel is in order so I can dyno and see if that helps. Handling made car faster but just could not get any rpms to carry on speed. I need long tubes and 3" x pipe and exhaust.
