Looking to purchase an Edge Revolution programmer for my 6.4L Diesel. Brother in law just bought a Diablo, but after reading all the "bad" stuff about this product, I'm not interested. Anyone out there have info or feed back on Edge Revolution. Had an Edge EZ chip for my last truck 03 GMC 2500 and loved it. Not sure if the Revolution will still allow for Regen cycle, as the truck is still on warrantee, so I'm not ready to R&R the exhaust components.
