Should I flash a previous Hemi fever custom tune after a dealership PCM update?

Thanks for any advice.

If you got a new ecu flash from the dealer, to be on the safe side lets update the tuning. Install a diablo tune then send me the new backup file and I'll update the tune

Thanks for quick response. Let me give you a little background real quick.

I had to take my truck in because of a radio issue. So I flashed my stock tune to the truck. When I got the truck back I tried to install the custom tune and The Trinity said that it wasn't mated to the truck anymore. So I assume it was updated at the dealership. Does that sound like what happened to you.?

tough to say. sounds like there might be an incompatibility with the old tune and new flash. Install a diablo tune and send me the new stock file
