All of the SCT chips, red or green can be reprogrammed at will. They are not vin locked in any way and are erasable and re-programmable millions of times.
Your gains depend on your car and how good your tuner is at squeezing every pony out of it.
We've been SCT dealers since the beginning. These guys really know their stuff.....and so do we. The company, SCT does not do the programming. They provide the dealers with front door access to the stock codes of the car. Then the SCT dealer makes the changes to the codes to accommodate what the car or the customer needs.
So you can get 5 different chips from 5 different SCT dealers and get 5 different tunes.
We specialize in Fords, so we can tune anything with a Blue Oval on the grill. This includes the SHO, Powerstroke trucks, Mustangs, Crown Vics, Town Cars, Escorts, Focuses, F-150s...you name it. We do conversion applications too. We're currently putting a 6.8L V-10 Ford truck engine in a 1970 Cougar.
Stranger things have happened.
$30 is cheap for reprogramming.
