Our Mustang performance chips and tuners are available for all Mustangs (as well as all Ford cars, and trucks) from 1986 through 2003. If your Mustang was built between 1986 and 1996, you will need one of our SCT 4 bank chips. Chips will also work in most Ford cars and trucks up to 2003. From 1996 and up, you have the option to use one of our many SCT flash units.
