    P59 BTR Stage 2 tune check Please

    Hello,

    I was hoping for a few suggestions on what to do next. I feel like the tune is close but would like a double check.

    3.70 gear
    Long Tube headers
    BTR Stage 2 Truck Cam
    stock injectors

    Start tuning more full throttle stuff.

    Could be leaving power on the table with such a rich commanded AFR and no real timing changes yet. Aim for 12.0-12.5 afr and lower 20's for timing at full throttle.

    You could disable brake torque mngt and increase the electronic throttle movement still. The brake TM could hold it back from doing a good burn out or powerbrake.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    @5FDP are you saying aim for 12.0-12.5 afr cruising or 12.0-12.5 at full throttle? Also, changing the brake torque mngt is done in system-system options- and change the value from 1 to 0 correct? Or do I need to change it under engine- torque management- general?

    Thanks

    For full throttle only. The EQ ratio looks stock still, which is rich. Lean it out to around 1.200 for starters and get the fueling to match the commanded at full throttle.

    Yes, that is how you disable the brake tm in the systems options.
