I don't think Rawze meant that you need to bring the truck to the dealer. Instead you have them bench flash the new ECM before leaving. If something fails in that process then they can replace the ECM before you even walk out the door. The purpose is to protect you from getting stuck with a defective ECM. Once it's successfully been flashed then you can just take it home and install it in the truck yourself. Just plug it in and go. If you need custom programming that can be done later, after the truck has run with the new ECM for at least 10 minutes.
