I have an Edge/Attitude installed in my LLY. Out of curiosity I bought a Predator and I would like to try it out. Can I just set the Edge to Level 0 and load the Predator? Or does the Edge need to be disconnected?

I loaded my predator with the edge installed. I beleive it was on level 3 at the time. Just make sure you pull the fuses recommended by diablo before downloading the pred tune. Since the engine won't be running the edge shouldn't have anything to do with programming the truck.

Thanks Kingslayer!

Shouldn't you be able to just pull your truck into a garage to load the Predator? In the manual they state that they do not want GM doing a diagnostic through OnStar while loading. This cannot occur when inside because OnStar runs by satillite and will not work indoors.
