This is what i think the main problem is. Alpha OBD has no way of communicating the the FCA database...witech does a restore based on what's in the online database, alphaobd can do a restore but it most likely restores to your stock configuration that I supposed is stored in the BCM or the app somewhere. I think you can do "offsite" witech restore, you just need the tool, a login, and internet. I haven't done it but it couldn't possibly take more than a few minutes to do. Unfortunately this means most of us will have to leave our truck at the dealer for half a day with explicit instructions on what to do. What I'm afraid might happen is I take the truck in and they "attempt to restore it" or not at all and say it's not possible to add the feature. This is when having friends at the dealer is beneficial...
but hey...this wasn't even remotely possible a week or so ago, so we can't complain too much about the process now, whatever it may be
