I have a used but in very good shape v2 that I used on my 2006 Dodge ram 2500. I don't have the truck anymore I haven't used for the tuner at this point and I have several tunes that were set for different vehicles one being my 2006 and another being a 2012 all were done by one of the beta testers here for EFI live back when it was created. If you're interested in the unit it has all the cords and everything works fantastic give me a shout 512-299-0981
