4L80E performance file?
I bought a 2001 1500HD with 6.0 and 4L80E. I'd like to get rid of torque management and make it shift a little firmer. I tuned my own Z06 a few years back but I've never messed with an automatic. Does anyone have any tips or a tune file I could look at with some of the important parameters modified?
