    On this model ECM you can do OS switching but you need to make sure the CalID is a match, that is what defines what the target vehicle is for the calibration (eg, 2500, Manual/Auto etc).
    Eg the CalID might be something like 55351430BH.
    What you are asking above is to go from a 2007 to a 2008 program, that might not work on the truck very well, I don't know.
    I no longer monitor the forum, please either post your question or create a support ticket.
