Under the main screen on the programmer it will tell you what rev. you have and another screen that will tell you what your computer ecm is ex. (2n2vxap). From my experince with this is if it runs fine now leave it alone, because the new update on the web might be the latest but only if your truck computer is the latest to match. But i do know that always make sure you return the factory tune to your truck. If you do not you will lose the tune when it rewrites the programmer.
