    If you're running the 4l80e, segment swap from the express van tune that has a 4l80e.

    Snapper - if you've done the 0411 PCM swap - there are both 4L60e and 4L80e 4x4 base tunes from the vans we use, on the tune repository. Let us know he you get along, we'll help.

    If your still on the old 96 black box, I don't know how to help with that one bud.

    Apologies guys, I've been out of the loop for a few months - started a new power plant build in Ohio,....been a little busy.
    Totally restored - 1996 GMC K1500 ext cab, HT383e swap, MPFI spider, 0411 PCM swap, FLT Level 5 4L60e with Sonnax Smart Tech input housing, Tru-Cool 40k transmission cooler with -6AN lines, 1-5/8" Hedman Husler long tube race headers with 2-1/2"ss dual exhaust, rebuilt 3.73 rear axle with Yukon/Detroit Helical locker, 6" ProComp lift with steering stabilizer and rear traction bars, 35x12.50x15 BFG All Terrains, Perma-Cool e-fans, etc, etc, etc,..
