sct x2
I have the opportunity to purchase a used sct x2 for $175. I own a 2002 FX4 with the 5.4l. The owner of the programmer says that "The unit is unlocked and has two Mustang supercharged tunes with four available tune spaces". I have no idea what this means. My question is what would I have to do to make this programmer work for me? Any reply's would be deeply appreciated.
Thanks
