I am going to be completely honest I bought this tuner with the car and I'm not sure if it is the X3 or the SF3, from what I've seen the X3 is the cheaper of the two and that's how I will price it. The pictures show the info about the program and 5 unlocks left. Absolutely nothing wrong with it, I just don't use it. $225 shipped. Preferred payment is paypal sent as a "gift"
