    It is one of LMM OS versions correct?
    You can do a full flash of the tune to change the OS but again is it made for the LMM?
    If you want it for your OS version you will need to do scripting. EFILive has info on scripting in the help docs on their site. You will need a stock tune of the new tunes OS to make the script then apply the script to your OS stock tune.

    Check this link out, it might help:

    I was written a while ago when full O.S. reflashes were not possible with '06 and newer trucks. They are now possible, but most of the information still applies. There's a link to LMM8594 in that thread. There's good information there as well.
