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

      2015-2017 GTs have dyno proven peak gains of 30 HP at the rear wheels on Bama Custom Tunes. By 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.

    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 2 dyno-tested custom Bama tunes:

    • 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 TiVCT 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, TiVCT, 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.

    **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.

    From what I understand, this tuner goes not come with the ghost cam programming. How do I get the ghost cam tune and how much does it cost? Also, can the ghost cam tune damage the variable timing components?


    • The Bama X4/SF4 Power Flash Tuner is capable of supporting a ghost cam tune, which can be requested through BAMA when submitting your tune information. We recommend consulting with BAMA to ensure your Mustang is capable of supporting a ghost cam tune. This will not cause damage to any valve train components, and is covered by the free tunes for life.

    I understand that the custom tunes are designed to work as the normal driving setting. Will I get any advantage by changing the mode to "track" when I get to the drag strip? Also, how long must I run my car after uploading the race tune before the computer adjusts all the trims? The track is 50 miles away. Is there a right way to do this? Thanks.


    • Since the custom tunes only change the normal driving setting, there would not be an advantage to changing the vehicle into track mode. When uploading a new tune, we highly recommend driving the vehicle through a full drive cycle to the computer to adjust to the tune. A drive cycle is typically 70 miles.

    I live in CA, will the tuner store my stock tune so I can switch back to stock tune if I need to have my car smog checked?


    • The Bama X4/SF4 Power Flash Tuner will allow you to save the stock tune on the tuner. So if you ever need to go back to the stock tune, you have the ability to do so.

    I have a 2017 GT with AirAid intake and Borla exhaust. I see in questions that the Bama X4/SF4 comes with one tune. Is that tune for a stock GT? Do I need to get the tune when I buy at first to match up with what I have in the car now? Or is that tune ok to use right out of the box? Or order it first with a new tune to match to what I have already?


    • When you order the tuner, Bama will send you a form with a few questions in regards to the modifications you have done on your car. You will supply them with the needed information so that they can create the custom tunes for your vehicle. The tuner will come with the custom tunes on it.

    If i tune my car with the stock air box and then i buy for example a jlt intake i have to tune the car again? And it gives the option to tune with an intake ?


    • Hi, A tune update is usually required when installing a CAI intake on a 15+ Mustang, to get a tune update emailed to you, you will need to order a Bama Tune File (Free Tunes for Life Members Only) Item# 38051 either over the phone or on the website and fill out a new tune sheet.

    I want to know if this fits a 2017 gt because i read the coments and i dont see any 2017 gt and i want to know if i have to download the tune in a pc or i just plug the tuner and follow the steps in the video


    • The Bama X4/SF4 Power Flash Tuner would work with 15-17 Mustang GTs. This tuner would come preloaded with the first custom tune. Any retunes in the future would need to be downloaded from a PC to the device.

      2017 Mustang GT 6MT

      Purchased with 93 Octane tunes. Because of some quirk with the X4 and the 2017 Mustang, the tunes had to be emailed after I sent in some information gathered using the X4 (minus 1 star for ease of use). The actual use of the unit is straight forward by following the easy to understand directions. The tune Pros: The tune feels strong. Throttle response is excellent - much better than stock. Power seems better, but it's hard to quantify. Installed with a TB spacer and CandL Racer CAI. Per the advertisements, this should equal 48 RWHP. Don't think it makes this much, but it's close. Note: The CandL needs a barrier between engine/radiator and the air filter - IAT runs higher than stock air box. The tune Cons: The only problem I have after two weeks of use is with cold starts. And no, I haven't contacted AM for an adjustment (yet). Cold idle is a little higher than stock. But, the main gripe is that, during cold run, RPM doesn't drop between gears. This makes gear changes a little awkward for the first few minutes. I can live with this if it doesn't get worse with fall and winter temps. Overall I'm satisfied with the results Yes, I would do it again. This has to be one of the easiest ways to get better throttle response and a little more kick.

      Bama X4/SF4 tune review

      Great service from AM and the tune guys at Bama! I chose not to use the supplied tunes but have a local tuner Sai Li to do the tune. My base was 382.62 / 365.50 and Sai moved it up to 402.32 / 375.53. Used a std Dynojet with std smoothing of 5. Run conditions: 81.64* F and 29.96 in-hg humidity: 27. This is not a race or performance tune but a combo and gives the best of both. Concerning performance parts on my 2016 manual GT which include a Airaid cold air intake ( no insert ) and the resonator delete with an FP X pipe, and Roush axel back mufflers. The base hp / torque is right in line with the 435 crank power with a 12 driveline loss. So I'm very pleased with the gains. The throttle response is very quick and you can feel the performance increases. Overall the performance gains is primarily from the tune and not so much the parts. I've learned not to believe the advertising but go with actual Dyno or track numbers.

      93 octane race tune is the tune to get. My automatic shifts hard and is ready to get up and go in every gear. This tune completely eliminates the lag time on the cars acceleration. The tune itself is nice and dropped my 0-60 down .90 seconds, but adding a CAI makes big gains in performance with the tune. This was easily the best $400 spent.

      The Bama Flash tuner. Arrived fast with 2 custom. I filled out a tune request and with my mods. When the tuner came my custom tunes were already in the tuner. The tuner is very easy to use. It only took a few minutes to load a custom tune into my cars computer. I'm looking forward to the free tunes for life program when I add more mods to my 2016 Mustang.

      It's name say it all Bama, Roll Tide

      All jokes aside, you get exactly what you pay for, be sure to fill out the vehicle details correctly, and you will receive your tuner with the files pre-loaded, and everything just goes as you would expect. Many updates required to the unit before connecting to the car, but that too goes as smoothly, no worries, if you use a cell phone and computer, you can handle this too. Easy... and the performance after the tune well worth it... and the tunes for life will come in handy as I do additional mods going forward.

Step by step written directions and videos are available for all functions (install, update, adding tunes, etc.) I noticed a huge gain in horsepower and torque. Haven't put it on the dyno to see the actual numbers, but it's a difference you can feel. I would highly recommend the product for its ease of use and multiple tuning options. Paired with Bama tunes, this tuner is amazing! Thank you to Bama for their quick response on tune changes and new tune requests!

      I can't believe what a difference this made with the custom tunes. I was a little skeptical about how effective they would be without Bama actually having my car and tuning it on a dyno but I'm very impressed. I have mbrp catback and a kandn cai on my new 2016 5.0 and before I installed the the X4 it ran great but it just felt like it had so much more waiting to be released. Bama raised the rev limiter which in itself made a gigantic difference. When the 5.0 gets into 7,000 rpm it sounds like music, everyone thats within a block comes running to see whats making that incredible sound. I dont know about mpg because I can't keep my foot out of it. I would highly recommend getting the X4 with custom tunes by Bama, they know what they are doing.
