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

    05-10 V6s have dyno proven gains of 16 RWHP and 21 ft-lb's of Torque or more 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 that 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.

Free tunes for life!
Every customer that purchases a tuner is enrolled in the "Free tunes for life" program.

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 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.

Do I need to swap my injectors to ford racing injectors before I tune it with this tuner?


Helpful (0)
  • Thank you for your question about the Bama X4/SF4 Power Flash Tuner w/ 3 Custom Tunes (05-10 V6). You will likely not need to change your injectors with the tuner. However, that will likely depend on what other modifications you have to your Mustang and your overall performance goals. We would recommend you call in an speak with a Bama representative directly. Bama representatives are available Monday thru Saturday from 9 AM to 7 PM EST.


About how much horsepower does the tune add if my car is all stock?


Helpful (0)
  • Hey Albert, It ll depends on the tune you select. i.e. 87 octane, 91 octane, or 93 octane and they all refer to the gas that would need to be used. the higher the octane the more power but on an all stock v6 car with a 93 octane tune you can probably expect some where in the neighborhood of 10-15 hp


I have a 08 v6 with a CAI and dual exhaust and I was wondering if when I got this if I would have to get a custom tune or if one of the three tunes that comes with it would be okay with my aftermarket parts

  • The Bama X4/SF4 Power Flash Tuner comes with three custom tunes, so you will be required to fill out a vehicle questionnaire form, so Bama can properly tune your vehicle. These tunes are specifically designed for the modifications that are on your vehicle, as long as they are listed on the vehicle questionnaire form. Attached below is the hyperlink to the questionnaire form for your custom tunes.


Hey guys I ordered my Bama tuner and expect it today but I've already gone and purchased some 4.10's for the rear differential which I didn't include in the information you asked for.How do I go about getting that change into my tuner so I can correctly install the gears?

    Like a whole new car!

    I was used to being made fun of for my 210 hp 2010 mustang v6. After a cold air intake, new exhaust, and now this tuner, I can easily beat my friend's 2013 camero v6, and I'm no longer afraid of bmw suvs or rice-y Hondas/Subarus at a red light. Be careful! The 91 octane race tune will throw you back in your seat and your tires will chirp between gears! It will take you into theach redline though, so maybe stick to the performance tune for daily driving.

    Ultimate Controlability in a Tuner

    I have modified the engine, transmission, driveline, differential and suspension on my Mustang. I first used the tuner from Ford Racing but I had problems with it disabling the computer when I tried to make custom changes. I was frustrated and went to a local shop to have it custom tuned for $500.00. The problem then was that I wanted to tweak the tune but it would cost more money each time I took it in. They also were not very encouraging about trying some of my ideas. I was again frustrated. I talked to a friend about American Muscle's BAMA X4 and at $400.00 I was skeptical about trying it. I read the reviews and talked to the tech department and it sounded like this was what I was looking for. I bought the tuner and they did the custom tunes to my specific instructions. When I received the tuner and flashed my Mustang it seemed to do just fine except the wrench lite came on. I called the tech department and the checked the computer and they discovered that the computer on my mustang was not the original one, it must have been changed before I owned it. They rewrote the custom tunes and emailed them to me within 15 minutes, I flashed the computer and everything worked with no problems. I have since tweaked the tunes many times with no problems whatsoever. I am so happy that I can make changes to so many parameters on my mustang. This tuner is definitely well worth the money and the tech department is awesome to work with.

    A MUST MOD!!!!

    I have a 2005 mustang v6 that was all stock. It had some pep but i was wanting more. Searching for mods and the best bang for my buck i saw the BAMA tuner on american muscle. After reading all the reviews i thought this sounds to good to be true but ill give it a shot. I bought it, received it in just a couple of days, plugged it in and HOLY #@!! Night and day in the performance and throttle response!! my car has 20" rims and tires and wouldn't spin them at all on dry pavement. Now i can light the tires up half way down the block!! This is a must have!! i wish i would have bought the BAMA tuner sooner because i have been missing out this whole time. Don't cheat urself out of horsepower and performance, buy this monster tuner NOW!!

    Born-again Mustang

    The tired, old 4.0 V6 in my 2010 convertible was embarrassing me, getting owned at traffic lights by Hondas, Toyotas, and even a Smart Car was getting frustrating! After installing this tuner, and the car's computer adapted to the tune, the car became a monster, I couldn't believe it! Combined with CAI, a 70mm throttle body, and miscellaneous other mods, I will no longer fear grandmothers, soccer moms, and an occasional teenager in his "tricked out" Scion.

    Great Product

    As time and budjet permitted. I have added modes such as the Ford Racing dual exhaust, switched to 91 octane and along with the Ford Racing CAI. I purchased the Bama X4/SF4 tuner which bought everything together. I keep it in the performance mode. It feels like a completely different vehicle. In a very positive way. My goal has been to increase my mileage, but to to have great performance when I want or need it. Thank You AM

On a WOT pull from a stop the tires actually chirp when the car shifts from first to second and from second to third, it feels like a whole different car, I couldn't be anymore satisfied with this product and the customer service when I had questions about the product.

    I installed this on my 2010 v6 after my x3 was stolen. You can definitely feel the difference between the stock form and having it tuned. This model has so many more features and it's almost half the size of the pervious version. I also have the JLT cold air, 70mm throttle body, 8.8 rear end with 3.73 gears and FRPP LSD, and Pypes mid muffler dual exhaust.

    First off, let me start by saying the shipping for this product was a mess! I ended up being shipped 2 of these because the first one was "lost" but later found out it was just delayed..Now, about the product. It is an absolute BEAST when paired with other mods. It's extremely easy to use, and honestly wish I had got this first over my true dual exhaust. The difference in acceleration and speed is very noticeable. The day after I put it on, someone next to me at a light asked if my car was a 5.0 because he could hear the idle rumble and the exterior designs I have does put that off as well..I told him no and he said I bet you can still fly. I took off WAY faster than I did with stock tune. Overall, I would recommend this product! There is really NO reason not to get this custom tune.

    I was doing a lot of looking around to see what the best first mod would be for my v6 mustang that would give me a little extra power. And a lot of people said the Bama x4/SF4. So I have that a try. Bama sent me an email and I had to fill out a survey specifically asking about my mustang. So these tunes truly are custom to what you have. When I first installed my 93 octane race tune, there was a huge difference. Difference in throttle response, shifting times and overall quickness. It made my mustang more fun to drive. And it is an automatic, so this tune makes my tires chirp when shifting into second and third gear when I'm pushing it! It's awesome! I would recommend this to anyone for a first mod. Great overall product.

    Fixed an issue

    I recived the Bama X4/SF4 with mixed emotions. To my surprise, that was stress I never should have been worried about. Not only did the tune improve my performance, it also fixed a small issue with in the transmission. I don't know how or why but after using the programmer, the slight dragging in the shifting stopped. This was an unexpected result. As far as the tune itself, I am very pleased at the response time and extra power. I'm not up to GT power but it will give them a run for the money. No more laughing at the 4.0.... Great job guys.

    Must Have!

    I have basic mods done to my S197 and I truly believe that a tune is a must have in order to wake up the car. I love the race tune, however it is in fact aggressive for just day-to-day driving. The X4 device itself is easy to use. The only concern that comes to mind is when first installing the device updater app for windows is to make sure the correct drivers are installed for your PC. All in all the X4 is a quality product and I highly recommend it.
