Bama Custom Tuning at AmericanMuscle. Power. Performance. Personalized. Proven
  • Power

    05-10 GTs have dyno proven gains of 17 RWHP and 18 ft-lb's of Torque or more on Bama Custom Tunes. By adding more fuel, optimizing the air/fuel ratio and tweaking variable cam timing, a Bama Custom Tune is proven to squeeze out the extra horsepower Ford left on the table.

  • Performance

    Drastically enhanced throttle response and a much more aggressive throttle map will dramatically improve your Mustang's acceleration, shaving tenths off your quarter mile time while throwing you into the back of your seat every time you smash the gas. Automatic transmissions will see an even greater gain in acceleration and drivability, as the tune adjusts shift points and firmness.

  • Personalized

    For each and every Bama Tune, we ask you 19 questions about your specific Mustang, including your unique set up and intended use, in an easy to use web form. This information allows us to write an entirely custom tune just for your specific vehicle to ensure we deliver the most power and performance possible.

  • Proven

    Our Bama Custom Tunes are developed in-house on our Dynojet 224xLC chassis Dyno. Hours of research and development through street, track and dyno testing/datalogging left us with fully refined custom tunes. The Bama Performance team has exclusive access to our inventory of parts.

Custom Bama Tunes specific to your vehicle. When you order a tuner, you aren't just getting a tuner - you are getting the tuner and 2 dyno-tested custom Bama tunes:

  • Performance V2 (87-93 Octane) - The Performance Tune offers a seamless blend of power, performance and drive-ability. Improving the overall driving experience of your Mustang, the Bama Performance Tune improves vehicle acceleration, increases power throughout the entire RPM and improves throttle response with revised timing, fuel, and VCT maps. Automatic equipped vehicles offer an aggressive shifting map to provide more aggressive transmission settings. This tune is suggested for the aggressive daily driver that is looking for more "get up and go".

  • Race V2 (91-93 Octane, E85, Race Fuel) - The Race Tune is designed for maximum performance and ensures the largest increase in vehicle performance. Using the highest grade of fuel available in your area is mandatory as timing, VCT, fuel, and throttle response settings are very aggressive. Automatic transmission settings implement entirely new shift points, torque converter changes and firmness settings designed for Track use.

Nitrous (91, 93, E85, Race Fuel) - Our nitrous option can be added to any of our previously mentioned tune options, but only for 91, 93, E85, or Race Fuel.

Technical Note About Fuel. Use of E85 will require larger fuel injectors such as Injector Dynamics ID1300 or Ford Racing 47lb/hr Injectors. Unleaded race fuel can also be used, but Stoichiometric points must be supplied.

**NOTE: Programming custom tunes may take 3-4 business days. We recommend ordering other products separately to avoid delay. Some heavily modified cars are not tunable with a mail order tune. Click for details.

What parameters will the X4/SF4 measure? This pictures show that this new tuner will measure several things on my car, but I don't see an actual list anywhere. I am looking specifically for air/fuel and boost gauges. Is there a list of what it will measure somewhere? Thanks!

  • The parameters that you can monitor would be determined when hooking it up to the vehicle as it will ping the computer to see what it can monitor. For a 2010 and older Mustang things like A/F would need to be monitored with an analog input and in most cases the same with boost. These can be wired into the tool to record this information into the LiveLink software or directly onto the display screen.

  • Unfortunately this is not something we do within the tuning. This is something you would need to do manually by holding down the traction control button with your foot on the brake as well.

    This was my first performance mod ( I started out with a 93 performance tune) and I have to tell you I was thrilled with the performance change. Throttle response was greatly improved, she's now pulling hard in 3rd, 4th , even 5th gear. The car is also running substantially smoother while saving 2-3 miles per gallon. This mod is a no brainer. Do it!

    I've never before used any kind of tuner before, and I admit I was very skeptical that it would make much of a difference really. I enjoy the lopey idle of a muscle car so I installed a set of FRPP Hot Rod cams in my '06 GT. It ran pretty well, but something definitely wasn't quite right. On recommendation from American Muscle, I purchased this tuner, hooked it up, and installed the software. What a HUGE difference! The car idles much better, the throttle response went from greasy slug to rifle shot, and I can feel the increase in power throughout the RPM's. Keep in mind, this is my first tuner, and it was so easy to use anyone can do it. Great product, easy to use, simple to adjust parameters.

    Great Starter Mod

    April 09, 2014

    I have read other reviews about just a tune increasing performance but I had not expected such gains. While the physical hp and tq gains are not huge you can feel every ounce of power and torque your mustang was holding back before. Heel-toe downshifting is a breeze, absolutely no throttle lag. The large screen makes it easy to adjust parameters and to data log. The device is very light and easy to store. SCT offers their LiveLink GenII software for true on road data logging which is a great tool to see the improvement and some of the adjustments such as spark advance and Air Fuel Ratio.
