    2016 8l90 first gear delete tune

    Is it possible to tune out first gear entirely on the t87? My setup is running 3.73 gears and it's extremely hard to get the 1-2, 2-1 happy part throttle, and first is pretty much useless at wot so I start in second on full throttle runs already.

    I've tried to set the upshift/downshift tables to 217/218 on the tables but it just causes it to act up and still use first.

    Any suggestions?
    Gear swap in the future, but at the moment I have what I have.

    Haven't ever tried that before, but what about setting the 1-2 to 0 mph across the board?
