Just too add, since there seems to be some confusion about the SCT unit, I'll just add two things about them.
1) You can use them as Scan tools on ALL (IIRC its all Ford products with OBD-II and I think even OBD-I) Ford cars.
2) When you buy one with specific tunes on them, they are VIN locked. Meaning if you have a 99 CSVT you can NOT go over to your buddies 99 CSVT and flash it and tune it for him as well.
3)IIRC, if you have a SuperChip they can pull that info off the chip and put in the SCT....
