I reprogrammed my 2007 GMC 1500 Z71 with this programmer last year. It is the same edition that is available now. It comes with a USB cable so you can download the latest upgrades from Hypertech as well. I traded the truck a couple of weeks ago and pulled the program off. Now I have no use for the progarmmer. As you will see from pics, it looks brand new and comes with all the original paper work. Below is the performance gains that I verify are TRUE! I got around 3-4mpg increase on regular gas. Save yourself some cash and by this one!
