Here's something I was pondering about, but don't know if it will work, anyone chime in because I don't know, just a thought.
What if you could get your hands on a new ecm from say a wrecked raptor from a salvage yard/junk yard, can you just tune the shit out of your truck, and if a problem happens, just swap out the ecm that never been modded/tuned?
It would not be a new ECM from a wrecked Raptor at a salvage junk yard.
