it's driving me nuts. I changed to the coil kit from 034 Motorsports, proper spark plugs, cleaned the MAF with MAF cleaner and the car still bucks like a banshee when you peg it to the floor.
Next thing I will remove is the G42 IAT sensor and clean it!!! Has anyone had this before???

AH ha!! That is NOT hesitation, that is bucking like a banshee = waste gate spring is probably tightened down too much. Is there a cap on the very center of the waste gate or has it been removed, as shown in the photo below. If you can see the Allen head socket, back it all the way up and try again. No bucking = turn it down 2 turns, try again. When you hit the bucking again, back it out 1 or 2 turns until the bucking goes away.

Assuming "thinga-ma-jig" = WG cap, then I suggest that you remove it (carefully, working those nuts off a few turns at a time - holding your hand on the cap to prevent the spring from pushing the cap off at the very end - hitting you in the face - has happened).
Then tell me if the spring looks like the one on the left or on the right.

But what about the pins on the harness connector? Look at the third one from the left here: It has come loose and is pushed in, preventing good positive connection to the MAF's male pins (Note G70 MAF sensor link under photo)
