I bought this from some dickhead (James from Jeep Camping if you know of him) that left the tune in his jeep when he traded it in but told me it was good to go. Long story short, I called Hypertech and they said they would put a new tune in it for 200. I'll take $50 shipped for it. It retails for 369+tax so for 250 you could be all set up. I would do it but I sold my Jeep.
