All he has to do is remove the tune from his vehicle, and restore the factory settings to un-marry the tuner. Then it can be used to tune the new truck. When done, return to mfr settings and then the original vehicle can be tuned.
You can go back and forth all you want, you just can't have two vehicles tuned with the same tuner at the same time.
