In an effort to get the vehicle checked out at Ford because of these CELs that I have been haunting me.... (Aka, I hope its not really bad) A Ford Raptor tech whom used to work at Ford said to remove the tune, put it back to stock and then undo the battery for 24 hours. He also mentioned to touch both negative and positive terminals together for about 10 seconds after the 24 hour period to ensure all juice was dispersed elsewhere. At this point, allegedly Ford cannot tell if there was a tune placed on the truck. Any truth or thoughts? Do.
