      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 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.

        4 2003 Cobra - 0310thCobra

        First time.

        Was easy to download tune. Was quick to upload into car. Haven't had a chance to go to a dyno to see what the real difference is with power.

        4 2004 Cobra - BrettD

        Instructions are not easy to find

        Once downloaded made a nice difference in throttle response. Nice options of monitoring cars important gauges. Car still needs to go to a Dyno shop to be totally dialed in.

        Cobra Tuner

        Product was very easy to use. The tuner that I spoke with at American Muscle was great, answered all of my questions. Tuner worked very well and matched the mods that we put on the vehicle. No a single issue.

        5 2003 Cobra - JayDee


        Was hesitant about getting this tuner at first but man, this tuner woke my car up by a lot, runs a lot smoother and picks up a lot faster.. perfect if you're going to be purchasing more mods because their tunes are excellent.. I would buy this again for another mustang in the future

        2 2003 Cobra - DylanR

        Its alright.

        Tuner is okay, confusing to use at first, not as easy to navigate as other tuners. Customer service from Bama is poor, difficult to reach anybody with knowledge to help you. Next time I will buy Diablo tuner.

        4 2003 Cobra - SVTBoucha

        Great product

        I installed a few aftermarket parts and my ecu wasn't cooperating. Got this guy and it fixed basically everything. My rpm's climb faster, better throttle response, plus it has active gauges which is helpful. Only gave it a 4 star because of the price.

      Is it okay to use this as a tuner after installing a smaller supercharger pulley? Will my car be safe?

      • As long as you are installing the smaller pulley onto the stock Cobra supercharger this will be able to be used with that setup.

      Can i data log AFR and Boost on my X4?

      I have a custom exhaust intake and im going to put a smaller pulley on the blower will this device put a custom tune in the car for all that ?

      What is the difference between this Bama X4/SF4 and the SCT SF4/X4? Is the only difference, that the Bama comes with 2 custom tunes? If I were to decide to get a custom dyno tune in the future, would this Bama X4 work for my tuner that uses SCT software? (I have an 04 Cobra) 1 answer
      I just ordered the BAMA X4/SF4. I currently have JLT CAI, SLP Loudmouth Catback exhaust, and I'm installing 2.70 blower pulley. What heat range spark plugs would you recommend. NGK Iridium IX seem to be the way to go, just want to see what heat range 7 or 8 and what kind of overall gains in HP would I be seeing with all mods noted above? 1 answer
