Hortence do your research, assumptions are always bad
You CAN switch to the older ECM. It HAS been done. BUT, you WILL loose your warranty because there is no way around "hiding" the fact that you had tampered with the system so guys cant just switch parts back to stock and have warranty coverage pay for their fun.
IF YOU really want to put a S/C, programmer or whatever on your truck You totally CAN do that but do it knowing YOU are responsible for your truck at that point.
