    Default Anyone have a good tune for 8 speed gas?

    Have a 8 speed in 2016 Silverado 4x4 with 6.2L and procharger. Over 500 Rwh. Here are current transmission issues:
    1. WOT shifts are often delayed/paused. Feels like engine is cutting out.
    2. Transmission up shifts too quickly with partial throttle. Tow/haul improves this slightly.
    3. Getting out of lots of throttle quickly causes the truck to lunge forward, like the converter is not unlocking.
    4. Manual shift tapping is useless and often sends truck into limp home mode from WOT shifting.

    Guessing shift point adjustment and removing torque protection is needed. Looking for a good tune to start with or pointers.

    Thanks
