okay that explains some of it but If I use the preset tunes at 0 for throttle boost it should be the same as modify stock tune with 10% throttle boost. Regardless what I am saying is that when I used preset 87 tune and any of the tcm's my truck bangs the gears pretty hard at wot. It literally feels ...

Okay. I have played with the settings some more. I added 10% throttle boost to the stock tune and I am pretty happy with the trucks performance.

Wonder if it's axle wrap. Just had a lift kit installed. Anyone else have problem? Guessing I could try leaf spring shackles.

Oh I forgot to mention that I loaded up newest software and gm tunes.
