I installed the 87 octane tune in my 2004 Avalanche 2500. I immediately noticed an increase in low end power but the 1-2 and 2-3 shifts were WAY too hard! I tried backing off the part throttle shift pressure from -5 then -10 and finally -25 with absolutely no change. I then turned the torque management back on with no change. It is shifting so hard I had to restore to stock until I get some input.
Should I try reinstalling again and starting over? Is there another adjustment I need to make? For instance what does "upshift MPH vs. TP mean????

Re: Shifting too Hard!!
I am really curious about this because I have the same truck and mine is doing the same. My computer crashed so I can't load the data...
Re: Shifting too Hard!!
Mike, here are links to the files you requested. This is the 87 octane tune with the only mod being my installed tire size.

Re: Shifting too Hard!!
diablo's CMR tuning software is what's used to open diablosport tune files - it's like hptuners/efilive tuning software...
and they're gone for the day now, so you'll have to wait until tomorrow when they're back in the office...

Re: Shifting too Hard!!
Still looking for help here. I posted the files as requested. Backing off on the pressures makes no difference in the shift at all.
