  • Power

    2011+ GTs have dyno proven curve gains of 50 RWHP and 47 ft-lb's of Torque and peak gains of 32 RWHP and 39 ft-lb's of Torque on Bama Custom Tunes. By adding more fuel, 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.

  • 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.

**NOTE: Programming custom tunes may take 3-4 business days. We recommend ordering other products separately to avoid delay. Some heavily modified cars are not tunable with a mail order tune. Click for details.

Is this tuner able to turn off the 02 sensors, I am getting long tube headers and off road x pipe, thanks for your help.

Do your tunes compensate for altitude? Are air fuel ratios or other parameters automatically adjusted for changes in altitude? I am concerned about having an aggressive tune loaded while on vacation. I live in the Atlanta, GA metro area, but may travel to Colorado or other western states with high altitudes.

PonyCar1919 Year: 2014 Model: GT

  • Yes, the tuners are able to compensate for different altitudes. This is a feature of the stock computer actually as it meters the incoming air it will determine the mass of that air. Since higher altitudes have less air mass the computer is then able to compensate for this.

    Exceeded all expectations

    I put in an Airaid CAI 2 years ago but didn't do any tuning; at the time I didn't have the interest. Plus, I didn't want to lay out that much money at once. However, recently the tuning bug hit me and I've been itching to tune my GT. I was all set to order the X3 but I saw the X4 had just been released and I figured for the couple extra bucks, there was no question to get the X4. The screen is very nice and crisp to look at. It is plenty bright whether you are in the dark or in direct sunlight. The wireless feature is quite handy as a lot of times, the USB cable isn't right there when you need it. The interface is very user-friendly and intuitive. I was sure to update the unit's firmware right away as that was recommended upon first opening the box and examining the contents. As for the tunes, I am floored by the amount the GT has woken up. I loaded the 93 Performance tune and just night and day difference over stock. I immediately noticed just pulling out of my street! Once I got on the highway, well all bets were off and in a split second I was over 80mph. Even my fiance was impressed by the difference! Once again, AM was great in answering my email questions and getting my X4 to me fast and Bama did an awesome job with my tunes. Thanks so much and I will no doubt be recommending and praising both of you.

    You can't beat free tunes for life and with the addition of the Steeda Cold Air Intake the "seat of pants" increase of performce was amazing. The tunes really woke up my 5.0 6-speed and I couldn't be more pleased with the results and the performance gains. I have the Track Pack with 3:73 gears and it feels like I gained substantial HP and feels like a different more powerful engine. I'm enjoying all the features of the new X4/SF4 Tuner and it's ease of use. Who would have thought it was so quick and easy to order Tunes for different octane ratings and receive them in an email so fast....I'm very happy with this product.

    This Tuner Is Amazing

    At first i was very unsure of getting a tuner 1. because my car doesn't even have 5 thousand miles and 2. because well would it really help my performance that much for the price? after some time I caved and ordered it. A birthday present to myself. best decision I could have made. took maybe 15 minutes to do everything. took it out right after, i noticed a difference immediately. Then when I took it out on a back road to see what changed through the power band it was night and day. getting this product is worth every penny!

    This tuner is awesome. The size is perfect for mounting in your vechile for data logging and monitoring. I paired the tuner with BBK long tube headers, BBK offroad x-pipe, Roush axlebacks, and Steeda CAI. The seat of the pants feeling is awesome. Tuner is worth every penny and I highly recommend it. A+ for ease of use and a thumbs up for Bama's awesome tunes!

    SCT X4 Programmer

    I was looking to add some extra muscle to my GT and bought the X4 as soon as it became available. I had read all the reviews I could find and even talked to the folks at SCT. The new X4 is by far the best programmer to date. Its ease of use and the new wifi capability made installing firmware updates a breeze. It can also be mounted in the car and coupled with the data logging ability, provides a easy to see read out. I would highly recommend this to anyone looking for a small, light, and powerful programmer.

    What are you waiting for!!!!

    I ordered my tuner from American Muscle. Process was easy and shipping was incredibly fast. After getting the tuner i filled up with good ole 92 octane and loaded the tune. The car responds so much better when hitting the throttle. The extra power and torque are fantastic. Its nothing to burn the tires down with the Performance Tune. But the best gain "in my opinion" was the gas mileage. I easily gained about 50 extra miles per tank of gas when driving normally. Thats a 1/4 tank Ladies and Gents. All in all I could not be happier. American Muscle thank you!!!!

    BAMA X-4/SF4 Great at all levels; price, performance, etc.!!!!!

    I was impressed with the advice I received on line from the technical and sales people from both BAMA and American Muscle. The product did as advertise and I got high praise for my choice of product with my main mechanic buddy who specializes in Mustangs. I built and played around with cars in the old days before chips and electronics so jumping into tuning up my 2013 Mustang GT was new. I was advised on the best product and the advice was spot on as the product delivered in all aspects. I don't race my car but when I want a little more out of it, this product delivers. I cannot recommend this enough and hope you are just as impressive as I have been. And you get free tunes for life in case you do any other changes!

    Not all that impressive

    After reading many, many posts where people raved about how great this tuner and the bama tunes performed, I purchased with high expectations. After flashing the new tune, I was equivocally unimpressed. While I realize that I don't have a great deal of power adding modifications, everyone that has used one has said they felt a real dramatic increase in throttle response and overall "seat of the pants" feel. In my opinion, I feel no difference whatsoever. Having built and owned a few supercharged Fords over the years, I know the value of a good tune and tuner alike. The x4 itself is a pretty good little unit, though it seems dramatically slower than an Xcal3 I used years ago. That aside, the interface is simple and easy to navigate. Basically just hit ok a few times, choose a few user adjustable options if you so like, and ok again and the process starts. The download of the stock program was slow, but it only has to be done once so that's no big deal. The upload was again slow, but acceptable. As far as ease of use, you could train a monkey to install tunes with it it is so simple. Perhaps I expected to much based on prior reviews, and I do believe that later on after a few more bolt ons that there will be benefits to be had, however I think at this point knowing what I now know I would have bought other products first and saved the tuner for something that required a retune to use. I did like the ability to change the rev limiter max, as I constantly hit it while performing "spirited" driving.

    Good Tuner, Great Support!

    Received my X4 fast due to quick shipping from American Muscle. The tunes were just as I had ordered but my speedometer was off by 10mph. An email to Bama Performance/American Muscle had a new tune out to me the same day to correct the problem, which turned out to be on my end and not the tune. I purchased my '14 GT used with 5k miles on it and have never seen a sticker or build sheet for it but it turns out that it was ordered with 3.73 gears instead of the factory default 3.31's. If anyone else has a problem with their speedometer on a 13/14 model, inside the driver's door, you will find a two-letter axle code: BB - 3.73 ratio CC - 2.73 ratio DD - 3.55 ratio GG - 3.31 ratio YY - 3.15 ratio Thanks again to American Muscle for sending me a tune that allowed me to find my issue!
