The biggest difference here, verses the mustang is we had a large group of people all with certain knowledge working together for a solution. It was a good deal of trial and error. Plus we had a freaking wire diagram... Lol.

I have spoke with Chris on this before on a truck forum, he has confirmed this fear. IF he programs the feature in and you take the car in for any update to the BCM it will flash over-write his calibration and you will lose the changes until you have him flash it again.
Also while the process of checking A against B to find the change to make, Chris is the only person I know of outside of GM that can program a BCM.
