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.

Ask a Question

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.


Helpful (1)

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.


Helpful (1)

Will the Bama tuner alone on a stock 2015 5.0 provide any gains? Also for the same 2015 5.0 is there a "Ghost Tune" available and do those tunes have any negative performance or drivability issues?


  • On a stock 15 GT you would see gains of about 30 RWHP. Bama does offer a Ghost Cam Tune. However it is a novelty tune, and can cause some drive-ability issues including some stalling, surging, or decreased fuel economy. BAMA Performance does not offer any revisions or datalogging to accommodate calibration symptoms of this nature produced by the Ghost Cam tunes.

    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.

    Great overall product and service!

    Very impressed with the Bama SCT X4! Super simple to work with, with lots of function. 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.

    bama tuner

    I never have gave a bad review on anything but first for everything. The tuner itself did exactly what is suppose to do especially after goin to bama website its easy to use. I know they said don't talk about the customer service just the tuner but that's where my trouble is. When I loaded the tunes on car I had a terrible cold start where stock the car would not go past 1500rpms but with the tune it was any where from 1700 to 2000rpms. I had hesitation issues. I have taken car back to stock tune, cold start seems like it use to be. I order Lund racing tune for lethal performance bc original that's the tuner I wanted in the first place. I paid 400 for the tuner and now spent 200 more for the Lund racing tune. I never had a problem with American muscle and probability never will. I will continue to shop here for mustang parts. The tuner does what it is suppose to do and I still can use the device with different tunes.

    After a mix up and receiving a defective unit, American Muscle's customer service imidiately sent me a new unit that I got in 2 days. Unfortunate to get a defective unit but it happens and AM's customer service continues to impress me. Unit is lighter than I expected it to be (that's a good thing) and it is very easy to navigate. I got it mainly for the ghost cam tune. Overall great device. I would recommend to a friend.

    Love the tune

    The tuner shipped and arrived quickly. I love the performance tune. I will never own another car that I dont tune. Tottally made the difference I needed. The car sounds better at idle, has better throttle response, and made the shifting much more smooth. Great product. Just as other reviews have mentioned I had trouble, because it needed to be updated right out of the box. It made it a little more difficult that it needed to be. I called in and Sean walked me through the whole process. Love the tune, but agree that it should come updated.
