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

    05-10 GTs have dyno proven gains of 17 RWHP and 18 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 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.

  • 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, VCT, 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.

  • Unfortunately this is not something we do within the tuning. This is something you would need to do manually by holding down the traction control button with your foot on the brake as well.

Can I use this on multiple vehicles at the same time I have 2 mustangs, Can I save tunes on it for both of them and use it on both of them? Thanks


  • No, these tuners will only load tunes onto one vehicle at a time. You would have to set the first vehicle back to stock to be able to load tunes onto a second vehicle.

    Great tune

    My automatic 2010 GT convertible is stock except for the pype bomb axle back exhaust. I purchased this tuner because I plan to add an off road h-pipe and hot rod cams in the future and would need it anyways. If you have an automatic, this will completely change your driving experience. I had 1/4 tank of 87 in the car, so I started with the 87 tune. This tune alone is a major upgrade over the stock tune from Ford. It eliminated throttle lag and the shifts feel quick. I can feel and hear the difference while driving. After filling up with premium, I tuned again using the 93 race file. I could tell a difference again upon startup and a quick Rev in park. Shifts are aggressive and fun when you want it to be. The exhaust note is more aggressive. I am very satisfied with my tuner and the tunes for life program. Tip: Windows 10 users should download the updated drivers and program from the Bama website in advance. It helps you get familiar with the process while you are waiting on the tuner to arrive.

    Junk. Wont connect to anything.

    Bought this a little over a month ago and have been waiting until I installed parts listed on the tune. I bought a couple extra and decided to use the custom tune for life feature. The email came through fine. I cant update the drivers no matter what I try though. My computer wont even recognize the device, let alone update the driver. I have gone through the instructions for updating for win 10 over and over again and nothing works. Crazy idea: Make it so it works on Win 10 so customers dont have to jump through all of these hoops. Win 10 has been out for a while now and none of my other tuners for my other vehicles have this issue on this computer. Only this tuner. I am EXTREMELY disappointed in this product.

    I had a customers mustang that was modded and another shop had flashed out the pcm back to stock. The customer was very upset because the car run very bad and the speedo was 20 mph off. I had Bama build the tune off my list and when I tuned the car all the problems were gone! Thank you for saving the day!

    I use the X4 with the 93 race tune which is nuts. The car just wants to take off and it sounds more aggressive after the tune. MPGs aren't to bad, but who cares about that when you just wanna go fast. Bama Tune is worth every penny and might be the best bang for your buck mod

    Wow! Just WOW!

    Okay.. So first off, the tuner seems a little expensive.. But once you apply the tune WOW. Okay, So i have a 2010 GT auto (boo) I know.. Mods include O\R X (no cats), CAI, and lowering springs. I spoke with one of the techs and asked if it is okay to apply the race tune for daily driving, he said yes. So I did. OMG. I've never had an automatic catch 2nd gear and chirp 3rd.. It drives like a new car. The torque difference is incredible. Fuel economy seems to be 1-2 mpg better. I was averaging 24mpg highway (mostly uphill) at 60mph, after passing 3 cars. If i drive normally 27 seems to be the number. The car seems to sound a little deeper (not placebo, didn't tell a friend what I did and he noticed.) Idle seems to be a little higher. The exhaust doesn't seem to smell as rich or strong. This tuner is definitely worth the money, I highly doubt you can find another mod for $389 that will wake your car up this much. If you use discount summerstang10 it gives $10 off on orders over 250 or more fyi.

    Not to satisfied

    I have had nothing but problems with my x4. I had problems installing my custom tunes to my car so I contacted the guys at bama performance to help me with this issue and they were no help at all. They told me I need to contact sct to wipe my device. Later that day I called sct tuning and the technical support gentlemen was not very nice at all.

    WOW.. 93 Octane tune..

    This tuner is a great way to wake up your mustang, I was really impressed at how much of a difference it made. Throttle response is much better, and pulls HARD into 2nd, 3rd, and 4th. It corrected my speedometer from my change in tire size, and the car FLYS now. Definitely a cheap mod for what it does to the car. Not to mention all of the other benefits that this tool does besides the tunes like obd, clearing trouble codes and reading your cars performance. Definitely a must have, and a big difference from stock.

    Worked Great

    The pros - It worked great. I have a very noticeable gain in horsepower. It's pulls harder through every gear including 5th. I ended up having the wrong computer code sticker on my ECU and bama customer service was great and walked me through getting the correct code and sent me the new tunes in less then 5 mins. Cons - I'm pretty sure I was sent a used one due to it not having instructions or the plack that the shipping info said would be in the box.

    This was the second mod i added to my car after a KandN CAI and let me tell you, there's not a second that goes by when i don't think about what a great decision I made when buying this. It made my v6 feel less like a slow 4 liter and more like a race car. The acceleration is amazing, and I'm pretty sure it improved my top speed as well. My only complaint is that it shifts almost a little too hard. The shifts jerk my whole car. My friends love it, but I'm not sure if my girlfriend feels the same way. This is a very minor complaint, obviously. If you want something to help you car come to life, this is it. I have never regretted this purchase and never will.

So I bought this tuner and my mustang runs incredibly well plus better fuel mileage after installing the 93 octane race tune. The street and performance tunes are much better than stock but I prefer the more aggressive feel, response and sound I get from the race tune. Great Product by AM. Will buy more upgrades from them.

    BAMA SF4

    This tuner is really simple to use. Plug in and select tune and let it do its thing. Initial first drive there is a noticeable difference. Eliminated check engine light due to removal of cats as requested. Since, I've added cams and switched to the race tune with a full tank of premium fuel. Haven't really been able to really get in car and open it up due to weather. Once I'm done with my planned modifications, I will run on dyno to see what hp/tq numbers are and I hopefully hit my target number!

    Great product for the money.Ive installed a few mods and this tied them all in flawlessly and I can feel quite the difference with the cars overall performance after uploading tune.I should have bought this first Because even with no mods such as air intake etc it still makes a performance difference with your stock car.It runs smoother at idle and during acceleration.Very pleased with this purchase and I'm very very particular with what I put in and on my 2008 mustang gt convertible.
