    Like I stated above Will at Overkill thought-

    It seems as though this is an issue with 07s using the older PCM box and isn't a faulty PCM. GM has likely changed how the fuel gauge is calibrated for the 07 model year.

    I would think that fuel calibration would be the same for 05,06,07???
