You can use this device, however you have to make sure its Unlocked/Unmarried! If he's still running the tune on his car, the device will be locked to his VIN number and will be no use to you. You would have to send it directly to SCT to be unlocked, which cost a fee of $150! However, if the device is Unlocked you can definitely use this device. You will just need to get tunes for your Mustang!
You can buy into our Free Tunes For life program for a one time fee of $150! I hope this helps, let me know if you have any questions or need some assistance. Our Bama Performance tuning specialists are here in the building Monday-Friday from 9AM-5:30PM EST and Saturday 9AM-5:30PM EST. You can hit them up directly at 888.226.9764 and they'll get you squared away!
