I'm thinking that if EDGE says it won't work, that's good enough for me. Sucks that you have to pony up even MORE money. Can you return it where you were mis-informed? I don't think I would play games in that department. Chevy has modified that ECU and surrounding equipment every year since the Duramax has come out!
I'd take THEIR word that it won't work!
