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

    03-04 Cobras have dyno proven gains of 30 RWHP and 35 ft-lb's of Torque or more on Bama Custom Tunes. By adding more fuel, 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 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.

Great tuner

Much better throttle response and pulls harder on the top end. It's very user friendly and well worth the money.

Nice Hp & Torque Gain

I got this due to a lean indication when my 03 Cobra was put on the Dyno at Lamotta Performance in Longwood FL. We brought the tuner and the car to him and it made a huge difference. Before: 412 RWHP

will this overwrite old tunes? recently bought car and dont know if it holds old tunes

Good Question (0) (0)
  • Many Cobras tend to have a chip in the PCM. You would want to remove that before using a new flash tuner or the tuner won't be able to connect to your PCM. The tuner will treat any tune on the car as the stock tune when you go to load a new custom tune to your vehicle.

    Good programmer

    Good programmer. I wish it had more gauges and a better way to arrange them the way you want. An off switch would be nice too so you can leave it plugged in all the time. Overall I'm satisfied.

    Great tuner!

    The x4 was great for my Mach 1! really felt it pull a lot harder after installing the tunes. My next purchase will have to be bigger tires on the rear so I can keep them stuck to the road!! Definitely gives it more torque and hp. Well worth getting it tuned!

    2004 cobra, acufab tb, jlt intake, basanni x pipe and cat back, port supercharger

    Good product easy to use. Just wish it came with the window mount as advertised by sct when advertising the product was being publicized at car shows and magazines. The ford magazines and you tube has plenty of tutorials on the product if you have any questions it came repackaged by bama tuning and I must say just the tuning for life made this a deal. Dyno tuning usually goes for around 400 and I plan on doing that later but the can tune works fine. The best feature is the data logging. The dyno tuners recommend this tuner also for its capatability to work with the sct maf.

    Bama X4/SF4, power with minimal install

    I received this product this week with tunes installed. All I did was plug it in follow the instructions and was done in a matter of minutes. You can feel the difference in your car immediately. The throttle response is a lot better. I would recommend this product to anyone.
