truck seems to go into REP mode at WOT. pulls all the way till about 4800 rpm then dies and goes into REP mode. Tune has been updated and removed but still does this. under normal driving conditions she is fine. heard this could be cause be low voltage but what do you guyz suggest. by the way i am new on here so any help will be greatly appriciated. The only codes it throws is U0107 "loss communication with Throttle Aculator Control"

Could be a tps sensor or the throttle itself.Check the pedal actuator

Bad pedal or tune. The tune is very picky on DBW setups to protect the driver from runaway vehicles. If you don't know what you're doing you can make the truck go into protected mode.

the tune has been taken off and she still does that only at WOT. i can accelerate kinda hard but if i smash it it will go into REP mode
Have you messed with the throttle body at all?
no i have not. i have already tried two different tb to no avail. it is an electric tb. first time it would do that it would do it cuz of a bad ground. all grounds have been checked. sometimes i have problems with low voltage and it seems to do it when ever i play the radio wit the engine off or i jump start someone
I just ported and polished a tb for my 04 that came off of another 04 and I get the REP at idle I cant even accelerate?????
