This never happened with the regular tunes that came with the cs, and i know i downloaded the calibration because i updated it and in the description it said "F150 - custom options" i had that tune in place of the tow tune. When i programmed my truck with the new tune i felt it run better than the canned tow tune that was in place before. Right now i programmed it back to stock, and the expected ship date was 11/10/11, but i didn't get to download the tune until around march.
My invoice # 5215
