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

      2015-2019 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.

    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 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.

    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.

      Awesome device

      I dont have much mods in my 2017 mustang gt. Just an airaid and and x-pipe and so then I purchased this bad boy and got a 91 and 93 tunes and let me tell you guys. I felt the changes. So far this bad boy is great and I would recommend this if you're looking to get the most out of your car and your money.

      Bama is best.

      Best thing I have ever done to my pony. Everything went to plan. Vincent and the guys were so helpful. Tunes were dynamite. When we hooked it up and mounted it on windshield the difference was night and day. All my mods down to the size of the tires were maximized 100 percent. Just bought a new GT. Getting ready to buy my second tuner. I could write a book on the advantages of the tuner. It's magic!

      Very Easy

      This tuner is easy to use and a great addition to the list. The tunes took a couple days to get bec for the 15 and up models they needed an internal code. So I had to wait for the tuner to come in the get the code, email Bama for them to finish the tune. I got the tune the next day. It really ties everything together and a great bang for your buck. The free tunes for life is what got me. Plus the added benefit of reading and clearing trouble codes is very nice as well.

      My 3rd mustang tuned by BAMA!

      Just wanted to give a BIG shout out to Shawn and the rest of the team at BAMA! Shawn and the team went above and beyond the call of duty, to make sure my S550 was/is running flawlessly. The tunes they sent over are AWESOME! The car previously had a 91 octane Roush tune on it. After installing the BAMA tunes, I was shocked in the difference it made! The car runs better and much stronger than it ever has before! The 93 Race tune is great, but the e-85 tune tops the cake!! Over the past several years BAMA has tuned my 04 GT, then a few years later my 03 Cobra, and several years later my 17 GT. BAMA knows their stuff, and I wouldnt trust a tune from anywhere else!

      If you plan on doing any mods to your coyote, this is a necessity. Almost all mods need a specific tune to teach the PCM how to use the particular mod or mods. I personally went with the BAMA for the tunes for life, I couldn't tell you if this is any better than any of the other tuners, but it does what I needed it to do.

      Very simple install. My 2015 GT is quicker and seems to shift smoother with the automatic. I cut the resonator off and installed an X pipe leaving stock mufflers. Bought an Airaid MIT which uses the stock air box. I installed a high flow dry AEM filter also.

      The hardest thing about the this was pulling the trigger. Once I did it doesn't get much easier to transform my 15 GT into the car I was wanting it to be. 1st of all everyone I dealt with over the phone was a pro. Thank You. The steps are easy to follow so long as you follow them which was a hurdle for me and my wanting to assume I know how to do things. Once I committed to go with the flow and follow the instruction tutorial it couldn't have been easier to install. Now the finished product is like the car took Viagra. I mean it's tough to explain without sounding to over the top. Remember you've spent $400.00 and to get this kind of result for that money is AWESOME. My 5.0 is a 6 speed trac pack and the difference is worth every bit the $400. Thank You Josh, Mark and American Muscle!

      Works great, easy to use but tune needs adjusted?

      Simple operation. My pony acceleration is not smooth when cold (surges). Although, it did it before the tune as well. Maybe a mass air flow sensor issue? Runs fine after it warms up (5 min?).

      Read my Review. ↓↓↓

      My review will touch on 3 things; The 93 Performance Tune, 93 Race Tune and Bama Service/Shipping. I ran both tunes for a minimum 250 miles. My GT only has a CAI, Cat-Back Exhaust and 11k miles... 93 PERFORMANCE TUNE (1 Star): is pretty much like the Sport Mode with less throttle response but more mpg savings. The Sport Mode was giving me 15.3mpg and the Performance Tune was 17.2mpg. So 2mpg difference between the two. It's was difficult for me to really tell the difference as a whole between these two (Sport Mode and Performance Tune), however the throttle response was better in the Sport . If you don't mind switching over to Sport every time you start up, then the Performance Tune is irrelevant in my opinion even with the mpg savings. So the Performance Tune is better than Stock, but pretty much the same as Sport Mode. If I had only received this tune, I would feel like I was robbed. I don't see myself using this tune again... BAMA SHIPPING (1 Star): It took 12 days to receive my email tunes, not 1-3 days like the email had said when I purchased the tuner or the 3-7 days the person told me over the phone. BAMA SERVICE (5 Stars): Free tunes for life. I mean, c'mon... 93 RACE TUNE (5 Stars): This tune is where the magic happens with the s550. If you want that pushed into your seat felling, use this tune. I didn't notice any mpg savings (15.2mpg) with this tune but I really don't care. It's that much better than the Performance Tune, Sport and Track Mode. With this Tune and the free tunes for life is why it gets 4 Stars. If it wasn't for the weak Performance Tune and the delay times in my actual tunes, it would easily be 5 stars.
