By far the #1 first modification for your 05+ Mustang is one of our aftermarket air intake and custom Brenspeed tune packages. No matter which air intake package you choose all of them feature a custom Brenspeed tuned SCT X4. Our custom tunes will give you the fastest throttle response possible, increased HP, the maximum torque possible at lower RPMÍs, and often improved MPG. BrenspeedÍs custom tunes are a far cry from your basic aftermarket tune. We have years of experience and R&D invested into our tunes to give you more benefits than just a peak HP gain on the dyno. With multiple modifications performed to many parameters within the torque management, adaptive learning, and drive by wire tables it is common to reduce quarter mile ETÍs by as much as a half second.
All of our packages include one custom tune developed for your Mustang and then that tune modified for 3 various octane fuels. This way you can run regular unleaded fuel if you desire or to take full advantage of your package by running premium fuel. The SCT X4 will store the factory tune so you can return the vehicle to stock at any time.
After you order our sales department will e-mail you to find out about your current modifications if any, your Mustang in general, and other information so we can develop your custom tunes. The custom tunes will then be loaded on your SCT X4 so all you will have to do when it arrives is plug it in and allow the custom tunes to load on your Mustangs PCM. It is that easy!

SCT X4 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 normal 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.
