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

      1999-2004 GT and Bullitt Mustangs have dyno proven gains of 21 RWHP and 34 ft-lb's of Torque or more on Bama Custom V2 Tunes. By optimizing the air/fuel ratio and tweaking spark 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.

      Designed for Race use. Bama's Race tune delivers maximum horsepower and torque with aggressive transmission settings and a sensitive throttle response. 93 Octane or higher fuel is highly recommended.

    Power and Performance. Now you can add dyno proven gains of 21 Horsepower and 34 ft-lb’s of Torque and improve the overall performance of your 1999-2004 GT or Bullitt Mustang with a SCT X4/SF4 Power Flash Tuner that includes 2 Bama Custom V2 Tunes. By optimizing the air/fuel ratio, adjusting ignition timing and tweaking variable cam timing, a Bama Performance Custom V2 Tune will squeeze out the extra power Ford left on the table. Automatic transmissions will see an even greater gain in acceleration and drivability, as the tune also adjusts shift points and firmness.

    Increase Your Mod's Potential. From the factory, Ford programs their vehicles to cater to the needs of the daily driver, not the performance enthusiast who adds aftermarket bolt-on modifications in search of more power. When making performance mods, you will need to recalibrate the vehicle's computer to realize their full potential. A Cold Air Intake kit alone on a 1999-2004 GT will net around a 5HP gain, but couple it with a Bama Custom V2 Tune and see dyno proven gains of 30HP and 40 ft-lb’s TQ or more.

    Free tunes for life! Every customer that purchases a Bama Tuner is enrolled in the "Free tunes for life" program. Any time that you make additional mods to your vehicle, our team of SCT certified Bama Custom Tuners will create new tunes for you. Just send us a list of the part or parts you've added and we'll email the new tune files to you.

    Bama V2 Custom Tunes. When you order a SCT X4/SF4 Power Flash Tuner, you aren't just getting a tuner - you are getting the tuner and 2 dyno-tested custom V2 Tunes that are written specifically for your Mustang and your particular modifications by Bama Performance. Bama even includes datalog reviews to ensure your vehicle is fully optimized.

    • 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.

    Compact Design. The SF4/X4 Power Flash Tuner measures in at 2.7” wide X 5.5” tall making it much smaller than the original SF3/X3 for easy storage in your center console or glove box. The cord is detachable and there is no battery or power supply needed. It uses the power from your vehicle's diagnostic port or computers USB connection.

    Full Color Display. The SF4/X4 Power Flash Tuner features a full color 2-3/4" diagonal LCD screen with user adjustable portrait or landscape modes. The SF4/X4 also has a convenient power saving auto dim feature.

    Built-in WiFi. The SF4/X4 Power Flash Tuner is now WiFi-capable meaning you will no longer have to plug it into your PC/Windows computer to receive the latest SCT firmware updates.

    Diagnostics. The SF4/X4 Power Flash Tuner can also be used as a diagnostic code reader. Save yourself hundreds of dollars each year by reading and clearing your own trouble codes rather than paying a dealer to do the same. Its as easy as a few simple steps.

    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.

    Application. This SCT X4/SF4 Power Flash Tuner with two custom V2 tune files by Bama Performance is specially designed to fit the 1999-2004 GT and Bullitt Mustang's equipped with the SOHC Modular 4.6L 2 valve V8 engine.

        Will this work after a engine swap? I own a 2000 Mustang GT 5 speed and was considering purchasing this tuner to wake it up some more. I am in the process of putting a new 4.6 SOHC motor in the car. If I buy this tuner and use it with the 4.6 already in the car will it work when I put the new engine in? The engine is just a rebuilt version of what's already in there.

        • The tuner would still work fine, there shouldn't be any issues with the tune working with a direct engine repalcement.

            Not happy

            I have a near stock 02 gt with a BBK cold air intake and a stright pipe exhaust and applying the 93 octane tune to my car which was in fact running more than 94 octane saw little to no performance gains whatsoever besides horrible horrible I cannot stress enough how horrible the gas mileage was. So I switched it back to the 87 octane street tune even though I was running 92 pump with octane booster. Only improvement I got was better shift timing while driving. Really disappointing

            Bama X4/SF4 Tuner

            First of all, for the tuner itself, it seems a little delicate In quality for the price. I just assumed it would be a little more substantial in the hand. Nonetheless, it’s very appealing to the eye, compact, it has a very nice easy to see and read screen. I like that you can adjust brightness and screen orientation. Very easy to use. I like that it has a code scanner built in for those times your wife says her CEL is on and you don’t feel like driving to the parts store for a scan. I also like the fact that you can fine tune the screen gauge layout to your taste of what you what to “keep an eye on”. Very intuitive piece of hardware. Very satisfied with the results.

            Great tuner and handheld. However Bama tunes are garbage and it would be wise to go with the x4 tuner with SCT tunes or just save your money and get your car custom tuned off a dyno.

            Great tuner for anyone that’s adding bolt ons on there mustang and doesn’t have a lot of money to get all of them at once as you can get a new tune each time you buy a new bolt on. This tuner does what it says and can really help you out in the long run especially if you play on boosting your mustang as you’ll need it to load a safe tune to take your boosted car to the dyno

            Not what I expected.

            Well first off, I understood you needed a PC/windows to do any kind of downloads/tunning because I have a Mac, and I was ok with that . The problem is, my device is locked up, displaying “ DEVICE COM ERROR”. Unfortunately, now I have to find a computer or buy one in order for the SCT technicians to fix. They have to log on into my computer while device is connected. My advice , don’t buy this. Just take your car to performance shop and have them tune it.

            This is more than your run of the mill tuner. Yeah it will hold two custom tunes but there is so much more you can see and do with the tuner. For example you can adjust spark advance, gear ratio, tire size, shift points and the list goes on. very happy with my purchase.

            Good gains

            I bought the Rev-X tuner and it didn’t work so I advise you to stay away from that device and go with the SCT x4. I called American Muscle and they replaced my Rev-X tuner with the x4 and I’m pleased with it. Really good gains, paired with 4.10s in my automatic GT. It corrected my speedometer, and cleared my check engine light. Shifts are really firm and crisp. I’m running the 93 tune and love it. My car used to chirp 2nd gear now it spins going into 2nd.
