  • 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.

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.

will this tuner support nitrous? will the tuner help me tune my air/fuel ratio for a specific shot of nitrous?


  • The tuner itself does not offer the ability to adjust AFRs on it's own. We offer custom tunes for up to a 100 Shot of NOS on a wet kit with our custom tunes.

Is it bad to use the race tune as a daily driving tune?

Remove the REV Limitation? Are there option in this tuner to remove the REV Limiter on my Mustang?


  • No, this is not something that you would be able to do or that we would do within the tune. Removing the rev limiter can lead to potential engine damage that would destroy the engine. We do however raise it a few hundred RPM's within the tunes.

Can this withstand heat? I was planning on leaving this in my car so I could change the tune without having to go all the way back home, but I'm afraid of ruining it with the Arizona heat. Especially with it being a black mustang.


  • These devices can withstand some heat but I would suggest if you are leaving it in the Mustang to not have it in direct sunlight. These devices, like any electronic, can overheat. If you store it in your trunk you should be fine but if you go to load up a tune and it is very hot to the touch you may want to let it cool off a bit before loading the files.

    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!!

    X4/SF4 Is a number five customer service I would Rate a number 10 I really can't rate any anything else as far as the performance or the racing modes because we haven't had a chance to really debug the system so far the first the performance tuning was the best the other ones are questionable others issues with first-year and second-year but I'd don't know if anybody could do anything about that.

    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.

    What an Improvement!

    I received the product over the weekend and installed the 93 Octane custom tune in my 2006 Mustang V6 Pony Package. I can only say the results were spectacular!!! The product was easy to use and took only about an hour to configure the tuner and make the changes to my Mustang. Well worth the money spent.

    Exceeded my expectations!

    I updated the tuner plugged it in to the OBD2 port and it was ready to go! The 87 tune was alright but when I uploaded the 93 race tune it woke up my v6 like you wouldn't believe. 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. Thanks SCT and American Muscle!

    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.

    Definitely worth every penny!

    I noticed a huge improvement in power with both 91 octane performance and race tunes from bama. If you are thinking about getting this for your mustang you should go for it! Whether it is your first mod or not this is a must have! Its great to be able to Upload your tunes on your own and bama helping you out by creating the tunes perfect for you. I combined this with a BBK cold air, SR 70mm throttle body, Pacesetter Long Tube Headers and a catted H pipe. My mustang is a lot faster! You can feel a nice pull now.

    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.

    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.

    The people writing the tunes, really listen to your wants/needs.

    After picking up a '05 Mustang V6 earlier this year, my first thoughts were to give it a little more pep. I bought a used CandL 83mm intake off ebay at a real good deal and had to have a tune, so I got the tuner a little ahead of budget plans. I received my tunes thru email only a few hours after the tuner arrived. I put in the performance tune that really surprised me. Not near like a V8, but a noticeable difference. After a few wks, I thought I would try the race tune, just to see. I was really impressed with the even quicker throttle response. But, there was one thing that really bugged me. A lot of the roads I travel here in Texas is 55mph. With the race tune, it will not go into overdrive til 68mph. So, I requested a 91 octane race tune, maxed out, but with the capability of going into overdrive at 54mph. This was not a normal request, so it had to go to technicians with more programming skills. About 48hrs later, it was in my email. I have been running it a wk now and I have to say they nailed my request. It will do the shifting I need to run the lower mph roads, but the pep when I want it. The best of two world came together, because the wife and I went for a ride today on July 4th, and to my surprise, with a race tune, I was getting 3 mpg better fuel economy than with the stock tune. Yes, if you are running blowers, turbos, nitrous, set up for nothing but race, yes, get you a dyno tune. But, for 98 who don't need a dyno tune, this is absolutely the best tune for the buck. And, when I upgrade the exhaust and then gears, they are there to set up my new tune. Thanks American Muscle and Bama. Great job guys!!! By the way, a 60 guy can still have fun!!!

    Very fast shipping and the product comes packaged very nicely. I set my car back to factory then uploaded the race tune to see how it would impact my Mustang. I did feel a slight increase in performance but my throttle response was still horrible. I feel like I gained more performance with just the install of my BBK CAI (no tune). The performance tune has slightly better performance than the race tune. I'm not sure if I need my tune re-written or if I just need more mods to feel a bigger impact in performance. I'm 50/50 with this product at the moment. I could've just expected more with all of the hype that is perceived in the other reviews.

    A Must Tune!

    The BAMA X4 was my first mod done to my 2005 Stang, and I have to tell you, I was thrilled with the performance change; I have only used the 87 octane tune, and it feels like a totally different car. Throttle response was greatly improved as well as the awesome increased of HP. I have an automatic transmission; they are usually sluggish, but now I have to be careful taking off from a complete stop so I don't spin the tires. This tune really wakes the car up and gives you power you can feel. It is a must!

    The torque is strong with this one

    I've only recently received my tuner and tuned my Mustang, so I have only used the Street tune thus far. However, I can wholeheartedly say the difference is very noticeable. Acceleration is much smoother, but also feels significantly more powerful than before. 1-3k rpm is where I felt most of the difference. As a college student, this hit my budget pretty hard, but it was certainly worth every penny.

    Woke up my 2007 V6 4.0

    Ordered the Tuner listing my current mods, came to me nicely shipped. Opened it up followed instructions as well as called customer servicer, had a few questions. I am currently using the performance Tune. It woke my Mustang up although I had many performance mods done prior to tune so the vehicle was already quick. The tune just polished up the performance, better throttle response and quicker acceleration. I would recommend this product for those who want a more exciting ride. Nice job AM.

    Them shifts though...

    I was so amazed at the speed of delivery of this product. Bama team programed it the same day I ordered it, plus it shipped on the same day too. So it arrived when it was supposed to be shipped, couldn't be happier thanks AM! Anyway, lets get to the product. WOW! This tune is so worth the money! My pony feels like a stallion now. I have a BBK air intake, a PowerAid throttle body spacer, Taylor street plug wires, Screaming Deamin' coil, and NGK spark plugs, and this tune wakes all of them up. I recommend this product especially to automatic pony owners! Now the manual owners can't laugh at my v6 auto because every time my car shifts I jump ahead on the road at least 5 feet! Its unbelievable! Everyone needs this mod! Only thing I can complain about is I didn't really know how to work the device seeing as it didn't come with any instructions. No worries though I got the hang of it pretty quick by just scrolling through all the options and now its as easy as winning a race against a ricer!

    This tune makes your car shift vigorously and really throws you back in your seat! My wheels actually chirp like a manual car from the second shift.... When combined with a pypes dual exhaust and a BBK CAI, the power gain is easilly felt and it's shown on the streets... My 0-60 time went from a 7.2 stock to a 6.2 with all of these mods combined. 1 second difference! I definitely recommend it to anyone, but combined with the other mods listed really wakes up your v6. The only downside is that the power was too much for my traction at first and my wheels would soon out like crazy. Think about adding some weight to the back or adding a limited slip differential to get both those tires gripping! The exhaust helped my traction for some reason??? Have fun!

    Hang on to your seat-this thing rocks

    I was skeptical at first, being a V6 and having so many other Mods not perform to the hype. However I believe in AM and their products, so I took the plunge and I haven't looked back. This tuner rocks....after a quick install I hit the road slow at first then WOT and was amazed at how this car woke up from its factory slumber. All I can say is if you love the power and like to be pinned against the seat in all gears then this is for you.
