Hi i have pullied and tuned 04 . i noticed that if im in third or forth around 3,000-4000rpm and i give about half throttle it hesitates and feels like the belt is slipping or hopefully not the clutch . Is this cus im im not in full boost ?? second gear no problem and high speeds through 2,3,4,5 is fine . I know its not like automatic where it gears down for u if u mash the throttle , but is this something normal in a boosted car ??
