    • Power

      99-04 V6s have dyno proven gains of 10 RWHP and 10 ft-lb's of Torque or more on Bama Custom 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.

    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.

    Free tunes for life!
    Every customer that purchases a 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.

    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 2-3 business days plus applicable shipping time. 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 is the actual performance gain on a stock 04 V6 with the Bama 91 octane tune?

        • On average, the Bama X4/SF4 Power Flash Tuner with a 91 octane tune we see gains of approximately 15hp on your model.

        I am wondering if I can use this tuner on multiple different vehicles. For example, I have a 2002 V6 Mustang manual, with minor mods (intake, exhaust, etc). Would I be able to tune my car and than use the same tuner and tune my brothers 2007 V6 Automatic with similar mods?

        • When you tune a car with your BAMA tuner, the tuner will marry to that vehicle, and will only be compatible with that vehicle until it is returned to stock and unmarried from that vehicle. You would not be able to tune two different Mustangs with one tuner.

            Makes your car a little less boring.

            Seeing mostly positive reviews i finally caved in and bought one of these. Im currently using the 87 performance tune and the car feels like a new car. Idles smooth, has noticeable power, and kicks you into the seat with the tire chirping shifts on the automatics. It is worth the money. Now to try out that 91 race tune.

            One of the best things I've done!

            So glad I decided to do this. After I put on the BB 65 throttle body I had an idle problem. It was idling to low. The tuner fixed that problem AND gave me noticeable power. Wither at a light or going down the road. You put your foot on the gas it goes. Right now. It will now spin the tires in every gear with a 3.8L V6 and a automatic. Plus it gives me more read outs on engine performance.

            This thing ruined my CCRM and later my ECU, first my AC compressor gave out shortly after installing the "so called custom tune" from BAMA, then my fuel pump gave out and left me stranded on the way to work, then my cooling fan failed to operate and I was having overheating issues, all of which ends up leading to my ECU needing to be replaced alongside my CCRM. buy this at your own risk, YOU'VE BEEN WARNED.

            Nice increase

            I have a 2000 V6. Never bought it for speed baught it to just cruise around with the top down. Did some cosmetic mods to it and very minimal performance mods. Not looking to try to be a V-8 wanna be just looking to increase the performance. Cold air intake, high flow catalytic converter‘s in a Y pipe from Flowmaster and a Flowmaster muffler. After I did the tune I noticed that I was getting up to a nice cruising speed at lower RPMs than previously. The shifting was a bit smoother and that 2 second lag after hitting the gas seems to have gone away. I did choose the race tune, I figured I might as well get the most out of the tune that I can. Probably throw a little race gas in from time to time. Other than that happy that the car is running more Efficiently with a tad bit more pep in the step.
