    How does my first tune file look? 2018 Yukon 5.3

    AFM turned off, Spark Tables smoothed, PE AFR/stoich, and trans settings all are the main changes. Everything on the car is completely stock.

    Trying to Figure out how to get less slip in the TCC. seeing 600-1000rpm slip at times when desired is at 0.

    Anything you guys see or where i can improve it Let me know!! Learning more and more every day.
