    15 silverado Pulling fuel at WOT to 14.7 a/f

    stock 2015 silverado 5.3L

    I'm having a brain fart.

    where in the tune, which parameter to stop having the s trims pull fuel at WOT.


    On dyno and each back to back run no matter what I do to PE or maf tables it's pulling to 14.7 a/f

    Lamda set to .82

    Thanks

    Way too many values maxed out.

    Look at your various peak torque values and make them realistic.
