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

Thanks and sorry for the long questions


Helpful (0)
  • For the tune to work properly, you will need to remove the o2 de-foulers, as the computer relies on that information to run correctly; so the Bama Tune will require those de-foulers to be removed. Additionally, having those de-foulers installed while running a catless mid-pipe, without a tune will cause the vehicle to operate improperly. Bama Performance will still create Ghost tunes for some applications, but we would recommend reaching out to their facility for application specific information. Furthermore, the Ghost Cam tunes have a standard lope setting;Bama Performance may be able to make some adjustments, however, we would recommend reaching out to their facility regarding that circumstance as well.

    Overall great product. Easy to connect and process new tunes into your vehicle. I would recommend that you always always. Make sure not electronics are being used lime radio or power anything. It will lock ur ecu up. Literally sit in ur car decide close doors make sure radio ac off all . Connect tuner and follow directions . Do not move! Haha but overall great tunerring aside from that crazy issue that it's so sensitive to voltage it needs to update ur car with new tune.

    Threw away $400

    First off let me say the techs who tried to help me were great. The tuner itself is fine but the Bama tunes are hit or miss and are cookie cutter tunes written on a test mule and may not work on your particular car. I went back and forth for close to four months with bama performance trying to get the tunes to work with my 2013 GT with no luck. I ended up having to go to injected engineering in kennesaw GA to get my car straighten out from the mess the bama tune did on my ecu. I ended up spending a full day of missed work and $800 on a custom dyno tune fixing what a $400 tuner caused to my car. Lots of guys claim they had good results with this tuner but I didn't and have heard a lot of others having issues as well. It may work for you but realize there's a good chance it may not and you will be stuck with a $400 paper weight like me.

    Exceeded expectations

    I had been thinking about getting a tuner for quite a while, but wasn't sure if the $400 for the tuner would be worth it. A friend of mine kept telling me, "man, you've got to get a tuner". I finally decided to order the tuner with an Airaid intake tube and Airaid throttle body spacer, already had Roush CAI and Roush exhaust. I went ahead and updated the tuner when I got it, which is recommended by SCT, which was very easy to do since the tuner has built in WIFI. While the tuner updated, I installed the intake tube and throttle body spacer. Once completed, I grabbed the tuner and uploaded the performance tune with 93 octane. Started my car and noticed the throttle response just backing out of my garage. I hadn't driven my car in about a week, so I drove it and let it warm up for a few minutes before getting into it, then I hammered it and OH MY! What a difference! Throttle response, acceleration, and even the sound of the exhaust was vastly improved. Went over to my friends house and let him drive it and he agreed it was a different car, and I haven't even tried the race tune yet. Definitely worth the dough. If you're on the fence like I was, I recommend getting this tuner, you won't be disappointed. Drove it about 150 miles over the weekend and even with spirited driving, my average gas mileage increased by just over 1 MPG. Very happy with this tuner and of course the service from AM. Ordered the tuner at 9:00pm on a Monday night and had the tuner with custom tunes by Friday afternoon.

    SF4 Tuner and AIRAID CAI

    I installed the Airaid CAI and S4/SF4 tuner today, and all I can say is, THAT is how the car SHOULD have run from the factory. I ordered the 87, 91, and 93 octane tunes, and installed the 91 tune today. WOW, it made a HUGE difference throughout the entire power band. I didn't realize how sluggish the car was until this afternoon. The car pulls very hard from around 2800 to redline, and is as calm as a kitten, below that. I only had Roush Axle-back Mufflers until today. I am Extremely Happy with the CAI and Tune. I cant wait to try the 93 tune in a week or two. The tune only too about 10/15 minutes to load, and part of that was downloading the stock tune into the tuner. I look forward to more upgrades in the future on my 13 GT. Do yourself a favor and do these simple bolt-on mods. You Won't be sorry

    Wow...What a difference this tuner made!!!!

    I have a 2012 GT automatic. This tuner made a huge difference in the shifting and horsepower gain. I really feel the car pull much harder and the shifts are nice and smooth. Tuner operation was simple and loading tunes is a breeze. The new color screen is a vast improvement over the old SF3. Anyone looking for a nice increase in horsepower and much better shifting should get one of these asap. Its a must.

    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.
