I'm looking to purchase a programmer for my 2011 Silverado 1500 with the 5.3 Vortec. I am leaning torwards the Edge Evolution CS. I know a few boys who have them in their Ford's and they love them but have said they eat transmissions which it is a Ford so you never know how much is the programmer and how much is due to it being built by Ford. Is the Edge a good product or is there something better? I don't know much about the computer stuff with the newer vehicles so any help would be greatly appreciated.
