I bought this tuner for my ford 6.0 diesel back in 2013. Programmed my truck once and never used it again. Tuner is LOCKED! It has never had an unlock used, so it has all five remaining. I do not own the truck anymore. It has the preloaded tunes that come standard with it. Has the manual and the cable for updating it and disc included. Please ask any questions you may have. Happy bidding!
