Trailblazer SS - WOT No Acceleration

Ok so here's the deal. Bought a RWD 06 TBSS off a guy with 115k. Car is beautiful except the person that worked on it before me was simply mechanically retarded. For instance, the radio didn't work before they screwed the antenna onto the stud/nut inside the cowl not the actual antenna.

Anyhow, guy before me said he paid the dealer to replace the trans, and it's a 4l70e or something. Have no way of getting a receipt but it does look new underneath.

I had a problem with hard shifting at first due to a faulty MAF (K&N oil got on it, and they descreened the old one)

Swapped the MAF, truck seems to shift much better now, no hard shifts or anything.
However, when I go to WOT, it downshifts and stays at like 5K and I go absolutely no where. It feels like something is limiting my acceleration, and I do not see a TC light flashing.

I have HPTuners so maybe I can take a datalog, but does anyone know why my car would flatline like that at WOT and go no where?
