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.

On Screen Data Logging and Monitoring. With a full color LCD display, the SCT SF4/X4 Power Flash Tuner makes it EASY to read the Built-In Data Logging or Real Time Monitored Vehicle Data, view popular sensor data such as EGT, Air/Fuel Ratio or any other 0-5 Volt source.

Easy to load; easy to restore. When you load your custom tune on the vehicle, the tuner automatically stores your vehicle's factory settings. To return the vehicle to its factory settings, just plug the tuner back in, select the option to restore the factory settings, and you're done.

Free tunes for life!
Every customer that purchases a tuner is enrolled in the "Free tunes for life" program.

Just send us a list of the part or parts you've added and we'll email the new tune files to you.

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 3 dyno-tested custom Bama tunes:

  • Street (87-93 octane) - The street tune is designed as a daily driver program that focuses on increasing mid-range power. Automatic vehicles are further enhanced by making adjustments to the transmission's shift points and firmness.

  • Performance (87-93 octane) - The Performance program is designed to add power at 3000 RPMs and higher, focusing more on the top end horsepower and all out performance driving. Timing, fuel and throttle response settings are slightly more aggressive than the street tune. This is a great track tune but also works well for daily drivers that are looking for a little more "get up and go" than the street tune. The automatic transmission settings are the same as in the street tune.

  • Race (91 - 93 octane) - The race tune will ensure the largest increase in vehicle performance. Using the highest grade of fuel available in your area is mandatory. This file is designed for "Race Use Only", as the timing, fuel, and throttle response settings are very aggressive. It is so aggressive that we do not recommend it for daily driving as it may cause your vehicle to try to jump out from a stop and easily spin the tires. On automatics, we implement entirely new shift points and firmness settings to further enhance the all-out performance of the vehicle.

Nitrous (91-unleaded race gas) - Our nitrous option can be added to any of our previously mentioned tune options, but only for 91-octane unleaded fuel.

**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.

    my girl asked if it made a difference. Well I hit second and was all over the road. I asked if she noticed a difference she said she couldn't tell because she was sliding out of her seat and trying to grab the seat belt at the same time. that was just with the 87 race tune.

    Get rid of that soft-natured factory tune ... permanently!

    June 15, 2014

    First, lets be realistic about the performance gains on the 05-10 4.6L ... it will not be massive ... but with a custom tune the gain is noticeable. Just wanted to clarify that, since some people have reviewed these products like they will be burning rubber all over the roads at ease. No, that will not happen. Either they have poor quality tires, or they're dumping the clutch left and right. However, these tunes do give the engine a little more get up and go, and definitely make a 200% improvement in throttle response. After driving with any of these tunes, it is impossible to drive the car again with that mushy low-grade factory tune. I was disappointed with the "soft" low-end power these engines make with a factory tune. I had a 5.7L Hemi in a 4K LB car, and that car had gobs more low-end power than our 4.6L Mustangs. Well, a good solution to our soft low end is a custom tune! I selected the 91S, 93P, and 93R tunes. I've loaded all three tunes and have driven each about 60 miles. All the tunes greatly improve throttle response, feeling more like a cable operated accelerator, unlike the factory tune which is greatly delayed. My street tune improved low end get up and go, and the car still pulls just as hard up top as the factory tune. Perhaps better, not too sure? The performance tune feels softer down low than both street and race tunes, but is at least a notch better than a factory tune. It pulls nicely up top, nothing mind blowing, but not anything I found greatly discernible over the street tune. The race tune seems to be the best tune of the three for performance gains and throttle response. It seems to make better low and mid power than the street tune, but up top I really don't feel it pulls any harder than the other two tunes? Maybe something is wrong with my tune file in that regard? Or it makes such a substantial gain in low and mid, that there isn't as much of a transition to top end pull as the soft low/mid tune from the factory? Still not sure? Anyhow, the throttle response on the race tune makes for a "touchy" gas pedal, but not anything I would consider difficult for daily driver use. It's true that it will increase the likelihood of a stall or lurch from a stop, but that is mainly because the throttle sensitivity is greatly increased and makes the driver more prone to oscillating their foot on the pedal. Of course the other two tunes are less touchy, but the timing advance and get up and go factor of the race tune, makes the increased touchiness of the pedal a non-issue. You just have to relearn the nature of the go pedal. That's all. As far as fuel economy between tunes I can't say, as I haven't logged each thru a full tank of gas with conservative driving habits, because the improved stronger pull makes me want to use it for now. I will see eventually... Overall this is a great product and worth the expense ... but only because this is the way these cars should have been tuned from the factory. BAMA had my X4/SF4 to me within a weeks time. The device is simple to use and leaves room still for adjustments, even to the custom tunes.

    An absolute must!

    May 17, 2014

    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.
