The Brenspeed Custom Tuned X3 includes one custom GT500 tune (for factory supercharger) developed for your Mustang and then that tune modified for up to two various premium octane fuels. This way you can run 91 octane fuel if you desire or to take full advantage of your package by running premium 93 octane fuel. The SCT X3 will store the factory tune so you can return the vehicle to stock at any time.

SCT X3 FEATURES:
Full User adjustability so if you so choose you can adjust idle, axle gear ratio, tire revolutions per mile, rev limiter, automatic trans shift points, spark, and air fuel. Your custom tune will not require any of these changes. We install the features on the programmer as some customers like access to them.

Ability to Receive Custom Tunes via E-Mail from Brenspeed
Expedite Option: Typically all custom tuning orders are built in the order received. We understand that our customers sometimes have to be to a race, car show, or just want it fast. Because of time sensitive events we offer expedited custom tuning for an extra charge of $49. We will build your custom tune outside of normal business hours in order to give you a one business day turn around. Your tune will still ship free of charge via UPS ground. If you choose this option please contact our sales department as soon as possible to provide us important tuning information.
We keep your custom tune on file so if you ever purchase more performance parts from Brenspeed you can request your current tune be modified free of charge. The free tune revisions are for new parts purchased from Brenspeed. We stock a wide variety of parts that are Brenspeed tuning approved. With a wide variety of parts on the market that are not tune friendly we suggest you speak with our technical sales team before you invest in headers, nitrous, superchargers, turboís, throttle bodyís, and camshafts.
