Ok. I'm not throwing any engine lights, car runs smooth as hell, hooked my snap on verus up to it and even that didnt give me any indication of any problems. But for some reason when you punch the gas it takes an unusually long time for the engine to decel back to idle. When I am actually driving and going through the gears at a relatively quick pace it sounds and feels awful, almost like i never take my foot off the gas when i am shifting. The Apexi exhaust makes it even more noticeable.

I already checked the cables, and cleaned out the throttle plate and all, anyone have any other suggetions?
 
does it do the same thing when you just rev the engine from under the hood with the throttle body?
