Recently got a DiabloSport InTune I3 tuner for the tahoe. Mainly for the ability to disable the AFM and get rid of the range device I previously was using. I am unable to figure out how to properly adjust the TCM, both the: Shift Firmness and Torque Management. I have adjusted both to the extreme in both directions and they appear to not make a bit of difference. Is anyone familiar with my setup and aspects of the intune device. I originally only flashed the ECM with the DiabloTune and AFM off. After that it seemed to shift differently (as in harsher shifts) I was used to the buttery smooth shifts and honestly kinda liked it that way.
