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.

Automatic equipped vehicles offer an aggressive shifting map to provide more aggressive transmission settings.

  • Unfortunately, Bama cannot tune for a supercharger as of right now.


why would the e.c.u. need to be flashed by ford? Also can I save my stock tune to this device? Do I need to get it wiped before each time I load another tune? Thanks in advance.

    Every part of this tuner is an improvement over its predecessor. If you've never owned a tuner it's perfect for you because of its simplicity. If you owned the previous model you know exactly what I mean. Impossible to be disappointed! Spend the extra money andsleep better at night knowing you did the right thing.

    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.

    Excellent upgrade!

    I received my power flash tuner and loaded the performance tune with no complications in a matter of minutes! I recommend this to everyone as a first performance upgrade on your Mustang. Throttle response is greatly enhanced and the power band has increased noticeably. Slight RPM fluctuation during cold start up but levels out in 40 seconds. I have not tried the race tune yet, as my GT is mainly street driven. Thanks AM and BAMA for a great upgrade!

    Must-have tool

    Never thought that such a small device in combination with a CAI would make you feel like you got a COMPLETELY different engine. Everything is better. Sound. Throttle response. Acceleration. Shifting (automatic). Before the tune, I was able to "safely" press the pedal to the floor. Now I have the freedom to choose between relaxed cruising or crash the car into the next tree. I did not use the race tune though, since the shift timings were way to hard for me (automatic). But the performance tune was great!

    Very satisfied.

    I got this tuner along with the JLT cold air intake. It made a very noticeable difference in the mid and high range. I am currently using the 91 octane race tune and the throttle response is so much better. this is about as good as it gets when it comes to email tunes. Highly recommend Bama. Great customer service! The only people I have heard talk bad about Bama tunes are the ones that have never used Bama before. It's also nice to have a code reader as well.

    What a Difference!!

    The Bama Tune was just what my 2006 GT needed, when I first uploaded the tunes the car did not run right but a quick call to Jose Garcia at Bama and it was fixed, I had forgotten to pull the reducer out of my Cold Intake that's all it was, once I did WOW I was all over the road . I notice a great difference in power at take off and mid range, I do see a slight loss in mpg but if your looking for gas mileage but a prius. American Muscle once again was outstanding!!!

    It definitely works

    I've read everywhere that this "wakes up the car" and didn't really know what to expect. Well, that's honestly the best description you can give. The throttle response is amazing now, it's ready to go when you hit the pedal. That sluggy feeling from a stop or a slow roll is gone, it's ready to move. It won't turn your stang into a Ferrari but it definitely gives those ponies some pep. Also opens the door for some bigger mods in the future, especially rear gears.

    Street Tune - 2008 GT, Auto Trans

    Recently bought a Bama X4 Programmer with a street tune. It wasn't cheap but I would have needed to drive 80 miles to Atlanta to get a one-time custom tune-up. This will be more convenient and I can update it on-line in the future when I get more mods. I don't have a lot of mods yet but I swapped the manual trans to an automatic, got rid of the cats, installed a CAI, installed Pypes shorty headers and Pypes axle-back mufflers. Since this is a daily driver, I asked for the street tune. It was easy to install the new tune. This programmer will not let you make adjustments while connected to the car. If you want to change something, you have to return the car to its original tune, make your adjustments while connected to your computer, and then reinstall the new tune again. I can definitely feel an increase in power and torque when I floor it. I'm having issues with the idle and sound at startup but I don't think that is a problem with the tune. There doesn't seem to be any decrease in mpg. Idle is loud around 1100 at start-up but drops to about 750 in 40 seconds. The questions that I sent in afterwards were all answered very quickly and professionally. Communication was great. I would recommend them and the programmer, especially if you are in a location that doesn't have a good tune-up shop available.

    Extra Performance? YES!

    My recently purchased 2006 Mustang GT in Screaming Yellow ran good, but just seemed to run out of breath after 4000 RPM's. I had an AirRaid cold air intake installed with the restrictor baffle installed from the previous owner. The car ran fine on regular gas, but just seemed anemic. After researching others experience with the Bama tuner upgrade, I was still a little skeptical, as other upgrades I had tried on different cars over the years seemed to have very little effect. You know, "WOW, YOU NEED THIS!" type reviews always left me disappointed after I GOT "THIS". LOL. I will have to say that was not the case with the Bama tuner. I installed the upgrade feature for the tuner on my computer before the tuner ever arrived. It took about 10 days for the tuner to get to my house after I placed my order and specified the particulars on my Mustang (CAI, plus SLP Loudmouths). Upon arrival, unboxing showed everything was there that was supposed to be. I removed the restrictor baffle from the AirRaid intake, followed the YouTube example for updating the tuner, and installed the custom race tune with no problems or issues. The performance gain, throttle response took place immediately. After driving the car a couple of hundred miles, there have been NO ISSUES with the tune, and the car runs like a race car, pulling strongly all the way up to redline. The performance gain is truly impressive, and I am not disappointed nor sorry I bought the tuner. A little expensive for only being a single use (or single car) tuner, but probably the most performance improvement you can get outside of a supercharger, or turbo addition. Ed Sullivan when he had a special guest on his program used to say "We have a really big Shoe (Show)for you tonight!" -Well, the Bama tuner was "A really big difference". :-) Thanks American Muscle!

    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.
