So I had a trans PCM miss match issue. I talked with HP tuners and got the latest beta version software that would allow segment swaps in the tune. I was able to swap the trans segment from a 2500HD 2wd tune with an 80E to replace the 60E segments in my Denali PCM.
Worked like a charm, took the sub out and it shifted like silk! It was nearly out of gas, drove about 5 miles in to town and filled it up. No hick ups no burps, ran great. Tune still needs some work, but its going down the road!
No hood got some funny looks
and with the 3.07 rear end, she is just chugging down the road at low RPM
