    Essentially what your feeling is as if you reduced static compression of your engine. While in higher elevation you can run more ignition timing without knock, but it may not compensate for how much...

    After seeing your log, my first reaction without even looking at the tune is dial in your LTFT's. Spend some time tuning VE than MAF using the How To's on this forum. Once you have the fuel trims as...

    If you could, do another log with your current tune while the truck is hesitating.

    At this point I would spend more time tuning VE and MAF tables. Refer to the write up's here on HPT forum for the...

    That's what I thought too, that's why I don't modify these tables at all. I wish there was a little more info on this TAC boundry vs Fried PCMs

    Under engine>torque management > General> Max Torque to 640. and the rest of the tables under it to something like 40,000,000
