    On a 4L80e you never want to have the shift selector is D4 when doing anything WOT, you run the risk of breaking the roller clutch.




    Side note, just poking around your tune you missed a step with your speed density setup. MAF dtc's need to be on first error and not second error for SD.

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

    If you don't want the light, just leave them unchecked.
