Recently I have decided I want to go with SCTs tuner and wish to get rid of my Predator. The reasons for this are because the place where I am getting my car tuned speciallizes in SCTs stuff and it would probably be a lot easier if I had their product, and I have heard that the Xcalibrater is a lot easier to tune your specific setup. Anyways, I was wondering if I would even be able to sell my Predator to another 05 owner and it work. I wasn't sure if they did something to it that locked it onto only your vehice, but I would think it would work for any 2005 Mustang GT. Does anyone know about this, I wanted to make sure before selling so that I don't rip someone off.
