I'll be doing it eventually, but it kinda got put on hold. I will be getting my own copy of HPT, so I will probably wait till then before doing anything that requires a re-tune. I also still do not actually have a TB, I have to wait until I go steal one off of a Colorado delivery truck or until I have the money for a used one.

My car is doing the same right now. I barely ported the inside of the throttle body and now it's throwing DTC P0507. And I have no way of tuning my car now

My car is doing the same as your car went it sit at idle.

since the throttle body raised the afr up one point, would this not be the same as adding a 2.9 pulley onto a GM stage 2 car but with out the heat??? i think it would, the only difference is you would have to change the scale for it to idle right.
