The Gears
The Gears

Improve ET's and Low End Torque. Installing a set of steeper rear gears is a great way to get more low end grunt off the line and lower your ET's at the same time. Ford Racing Mustang ring and pinion gears feature a super strong forged construction, CNC cut & lapped gear teeth, and a black oxide finish to resist corrosion making them perfect for street, road, or race use. More info about these gears - Here

Kit includes: (click on each item for full product description)

Increased HP and torque. From the factory, the manufacturer programs their vehicles to cater to the needs of the daily driver, not the performance enthusiast. After loading the custom Bama Tune on a vehicle, even a bone stock, unmodified Mustang will realize noticeable gains in HP, Torque, and Fuel Economy.

Increase your mod's potential. Factory computer settings are calibrated for the original factory components. When making performance modifications, you need to recalibrate the vehicle's computer to realize the full potential that these modifications can achieve.

Free tunes for life! Every customer that purchases a tuner is enrolled in the "Free tunes for life" program. Any time that you make additional mods to your vehicle, our team of SCT certified Bama Custom Tuners will create new tunes for you.

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 2 dyno-tested custom Bama tunes:


  • 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 VCT 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, 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.

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.

Easy to load; easy to restore. Not only are the custom tunes easy to load on your vehicle, it is just as easy to restore your factory settings. When you load your custom tune on the vehicle, the tuner automatically stores your vehicle's factory settings. To return the vehicle to its factory settings, just plug the tuner back in, select the option to restore the factory settings, and you're done.

Bryan

  • The Bama X4/SF4 Power Flash Tuner w/ 2 Custom Tunes and the standard SCT Tuner are the same device. The difference between the two are that the SCT device comes with standard tunes for light applications, where the Bama device comes with custom tunes, which are tunes specifically designed for the modifications on your vehicle. Additionally, it includes a free tunes for life membership that allows you to change parts on your vehicle and receive a new tune for optimized performance and efficiency.

At my yearly inspection I have concerns about my car running improperly due to mods put in and tune. Can you set car back to factory specs to get the sticker and go back to the tune set for mods that were installed?

  • You have the ability to set your car back to the factory spec tune. You will need to have that set from the tuner before taking in for inspection.

I am replacing the entire axle housing on my 14' GT. It appears this kit has everything I need for the housing swap. The original housing has damage.

  • The Motive Rear End Installation and Bearing Kit - 8.8 in. (86-14 V8; 11-14 V6) comes with everything you need to replace your rear end. The only other part you'll need, since you have a 2014 Mustang GT, is going to be a Ford Rear Gear Pinion Bearing - 8.8in (10-14 V8; 11-14 V6), item # 52994, (http://www.americanmuscle.com/88-gear-assembly-2010.html).

    Perfect!

    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.

    Review from Bama X4/SF4 Power Flash Tuner w/ 2 Custom Tunes (05-10 GT, Bullitt)

    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!

    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.

    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!

    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.
