DERTY

Alright, I couldn't put the whole symptom in the subject so here goes.

Whenever I am driving the car and I shift into neutral while rolling the RPM's either maintain or climb towards 2000 to 2400 until I come to a complete stop. When I rev the motor I don't get quick RPM snaps I get a really quick ramp, but the engine takes it's sweet time coming off RPM.

I do have a ported throttle body and it has the drill mod done so that it can idle. We did that when we did the heads and cam. Anyway, it purrs like a kitten in the driveway at idle, really nice! But it's driving me crazy that it does that on the street. Anyone know what could be wrong?

Check for leaks around the maf. My car did that on my cam and headers setup, but that was because I drilled the hole too big..

Sounds like a vacuum leak. Or your TB hole is WAY to big.
