    At first glance, ECM file is a stock file with all the torque limiters stilled turned on. I compared it to another stock 2015 I found in the repository. Same with the TCM.

    Probably something wrong with the magic in the background.. I would go back to your tuner to have them revise it to fix the issue

    chances are, your tuner just has the codes disabled but you're still running in a "reduced engine power" in the background
