A “mail order” or emailed tune can unlock the full potential of your Mustang or SVT Lightning by making appropriate changes for cold air intakes, larger mass air meters, off-road exhaust systems, or rear end gears. These custom tunes are perfect for the simple bolt-on type of vehicle. You can also use your SCT Tuner to upload custom dyno-calibrated tunes at your local tuning facility. These are great for forced induction and power adders such as nitrous oxide.
