You should use the GTP pcm because Overkill may have setup tables that HPT won't let you at to copy over to the GT pcm (i.e. you need to use TinyTuner). Plus if you use the GTP pcm, you should only need to do a "Write Calibration".

I have never used the "Write Entire" option but I know someone else who did and the pcm end up bricked because the car's battery wasn't fully charged.
