    MAF dtc's need to be set to MIL on first error, not no error reported.

    Are you using the 2016 MAP sensor? If so, those MAP values are likely different than the 2008 4.8 computer settings.

    Copying 6.0 stock data over a 5.3 stock tune shouldn't be causing any sort of real issues if the 6.0 is indeed stock.

    Go back to your stock throttle body and see if the lights go away. If they do, then you likely found your issue.
