FWIW, when using HPTuners, I cannot change the accelerator pedal/throttle angle map without it triggering a REP.
I made some changes upto around 10%-15%. Have heard smaller changes might sneak by, but some other setting checks throttle/accelerator position and triggered a REP. The REP mode is so handicapped, I feel it's unsafe (6% max throttle from 50% accelerator position upwards, 1-5% throttle from 18%-50% accel pedal)
To change any throttle area maps, there is this disclaimer..
"[ECM] 33034 - Desired Throttle Area - RedPwr: Reduced Power Mode Desired throttle area based on pedal position and RPM or VSS (pedal to throttle map). WARNING!!! Modify this table at OWN RISK. Incompatibility of this calibration with the vehicle TAC module calibration may render PCM permanently inoperable."
Not worth the risk for me!
Here's some settings I can see in hptuners..
I might change the throttle increase area rate for 1st gear (1, 4, 8, 100, 100) (no disclaimer, usually all 100's in cars, 1,50,100, etc. in escalades 6.2 tunes I've seen)
