Dustin- why unplug all the A/C stuff?
Re-set the computer by pulling the battery cables off for 15mins or so. It will have to re-learn how to idle and how to drive, so let it find the idle which it should then take it out for a cruise that should help. I agree with checking the TPS and how much FP are you running? I didn't see aftermarket heads in your combo, those stockers will hold you back with a ported intake, I think that is a much bigger bottle neck then the stock TB.
