    Review & Installation Video

    Justin: Hi everyone, Justin with AmericanMuscle.com with Paul from the Bama Performance Team here to talk to you about the benefits of using the Bama SF4 Flash Tuner loaded with the custom Bama V2 Performance and Race Tune on your '05 to '10 three valve GT. Now, Paul, obviously the main benefit or purpose of using an aftermarket Tune is to make your car faster. How is the Bama Tune going to help in that regard? Paul: When we're calibrating a vehicle, we've got completely different expectations and regulations than the factory, and the OEMs leave a lot on the table, and there's just a lot for us to do. So we're modifying the fuel maps, spark maps, a complete reconfiguration of the drive by wire systems. And for the automatic guys we do a whole new shift schedule map, torque converter changes as well. Justin: Very nice, and now we're doing the Performance and we're also doing the Race Tune. Can you explain the differences between the two? Paul: Correct. Our Performance V2 Tune is really designed for that daily driver or the weekend warrior to offer a seamless blend of driveability and maximum power whereas our Race Tune, that's pretty much maximum power, maximum torque leaving nothing on the table with really aggressive throttle response, really aggressive shift schedules; for the automatic owners, really sensitive throttle, pretty much disabling all of the torque management and some other additional modifications that we make. Justin: Very cool, very cool. And what Paul didn't mention, of course, is that with Bama's Free Tunes for Life, as your car's modifications grow, Paul and his team will write a new Tune for each and every mod so that you can get the most performance out of your setup. So Paul's going to get out of here for now. I'm going to talk a little bit more about the benefits of the actual SF4 Tuner itself, but then we're going to run the car, the '07 GT behind me, and we'll see what kind of numbers you can expect. Breaking down the Tuner itself, you can see the SF4 does feature a compact and sleek design with a rather large full color LCD screen. Now, that screen is fully customizable and offers different colors and themes available through the menu. Now, another nice thing with this large screen is that it does feature a landscape mode. You can even turn the Tuner sideways for a different view which is helpful during datalog sessions as I'll talk about in a minute. So why the larger screen? Well, as I just mentioned, the SF4 does feature on-screen gauges and data logging similar to what you would find on more expensive models, like the ITSX or even the SET Live Wire, for instance. Now, the on-screen gauges are fully customizable as is the layout and is capable of displaying up to eight different values at one time, including your car's air fuel ratio, boost, intake, air temperature, and RPM, just to name a few. And again, all of which can be data logged with a simple touch of a button. Other features with the SF4 do include built-in Wi-Fi which is a nice little touch allowing you to take care of this future firmware updates wirelessly. The SF4 still can hold up to 10 Tunes at one time like previous Tuners, and it is still capable of reading and clearing those diagnostic trouble codes, again, just with a simple touch of a button. Now, guys, if you do have any more questions about the SF4 itself or about the new Bama V2 Tunes, I strongly encourage you to head back to the product page at AmericanMuscle.com, if you're not there already, to read up on some more details. But more importantly, you can read up on what other three valve owners are saying about running a Bama Tune on their own ride. Now that you know a little bit more about the Bama SF4 handheld Flash Tuner, let's find out just how much power you can expect out of your '05 to 10 GT with the help of a custom Bama V2 Tune. First, I'm going to walk you through the process of uploading your Tune. Then I'm going to get Paul back in here, run the '07 GT one more time and just see what kind of numbers we can expect. First thing you're going to want to do is locate your car's OBD2 port. Now on the '05 to '10 cars, it's going to be on the left-hand portion of the dash underneath. So go ahead and plug the Tuner in and wait for it to power on. Now, once the Tuner actually powers on, you're going to want to navigate to the Tune you wish to select. Basically just hit the Okay button a few times to make sure the key is on. Then we're going to go ahead and upload our Bama Race Tune. We'll select that one. It loads it, and then basically from there you're just going to follow the directions listed on the screen here, and you should be good to go. Now if you guys should have any questions or problems about uploading your Tune here with your '05 to '10 GT, don't hesitate to reach out to a Bama tuning expert. So with our baseline run already in the books and the Tune uploaded, Paul's going to hop back in the '07 GT here, make another hit on the Dynojet just to see what kind of numbers you guys can expect with your ride. Our baseline run with our 2007 GT gave us 269 horsepower and 296 pound feet of torque at the rear wheels. With the Bama Tune uploaded, the corners now making 283 horsepower and 310 pound feet of torque at the rear wheels which makes for a peak gain of 14 horsepower over those baseline numbers and gains of 17 horsepower and 18 pound feet of torque throughout the curve. All the bolt-ons in the world won't do anything for you or your ride without a quality Tune to bring it all together. So if you're looking to truly maximize the performance of your '05 to '10 three valve GT, then you're going to want to check out a Bama S4 Tuner loaded with the BAma V2 custom Tunes here at AmericanMuscle.com.

    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

You can also save money on your installation labor by having your Trac-Lok rebuilt at the same time as your gears are installed, see drop down option above.

    **NOTE: Programming custom tunes may take 2-3 business days plus applicable shipping time. We recommend ordering other products separately to avoid delay.

    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 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.

    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.

    I have read the contents of this kit, I have watched the video, but I STILL DON'T KNOW if this kit includes the rear gear pinion bearing kit necessary for 2010 Mustang gear swaps? And this is from a person who reads, writes and interprets complex written language for a living... Also, can not find this "drop-down" menu you are talking about in the video. You warn about it being necessary all the time, yet do not state clearly if this bearing kit contains it or not. Please indicate this CLEARLY for everyone to see, it is really confusing. Apart from that (assuming the kit DOES NOT include the rear, which I seem to deduct from one of the answers for previous questions), why make a bearing kit without the most important and needed bearing? Does ANY kit you sell include this 2010 rear gear pinion bearing (maybe those big kits with bottles for 279$ or any other kits by Ford?) or the only way is to buy the bearing separately?

    • We do apologize that the listing is not clear enough. The Motive Rear End Installation and Bearing Kit does not include the Rear Gear Pinion Bearing for 2010-2014 Mustangs. The bearing is not included in the kit because the kit is designed for 1986-2014 Mustangs, and it is not necessary for the majority of the years this kit works on. It is included in the Gear Combo Kits for the 2010-2014 GT and 2011-2014 V6 Mustangs found here: https://www.americanmuscle.com/2010-mustang-gears.html#shop-by7

    Just installed the JLT CAI on the weekend and loaded the Performance tune. I really like it so far but have a question about the Race tune before I install it. The traction control on the Mustang has saved me a couple of times, especially in the wet - does the Race tune turn off the "electronic nanny"? I actually am glad I have the nanny for day to day driving and don't want it disabled.

    • Your traction control system will still be enabled on the Race tune. We have modified the torque calculation and clutch protection logic as well as a few other changes specific to the race tune to unchain the performance of the car with racing/competition in mind. I would recommend giving it a try and then running the tune you prefer - either your Performance or Race tune.

      Easy install, makes a big difference

      Once I figured out that I had to download the tunes from an email everything was smooth sailing. I got the 87 Performance tune and the 91 Race tune. Haven't had a chance to try the Race tune yet, but the Performance tune kicks a**. Throttle response is quicker, acceleration is much quicker, and modified shift points allow the car to rev out a lot longer which results in a faster car with less throttle.

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

      Great product

      Easy install, really woke up the car. Revs out higher, better throttle response, smoother idle. Ran a tune to calibrate for my new off road x pipe and no check engine light has been present

      This is a great way gain a little extra hp/tq without having to do some major engine work.. I love this x4 throttle response is amazing.. Gas mileage increased I’m running a 89 performance tune and I’m happy and love what my mustang is becoming still have more work ahead to gain big hp /tq gains but this x4 will really wake you pony up and allow it Gallup be free ..

      Works great

      Huge difference from Stock. only other mod is cold air intake. both 87 and 91 octane tunes really add some punch to low, mid and top end. Very easy to use.

      Review from Motive Rear End Installation and Bearing Kit - 8.8 in. (11-14 V6; 86-14 V8, Excluding 13-14 GT500)

      Great kit, has it all!

      This kit is eveything you need to install your gear and pinion. Bought it with the royal purple gear oil, 3.73 gears, and the ford friction modifier because their complete kit was out of stock. Great buy, great deal, great product.

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

      2009 Mustang GT with 87 perf and 93 race tunes

      My GT is stock except for Roush CAI, 79K miles, new set of OEM SP-509 spark plugs, 5-speed manual trans., and P245/55R18 tires. I normally run 89 octane due to pinging on 87 octane factory tune. My aim was to eliminate stumbling and hesitation under hard acceleration. So I reviewed several tuners before settling on this one. I'm a first-timer with tuners, so this was a learning experience. I received the tuner programmed with two customer tunes: 87 Performance and 93 Race. After learning about CAI reducers and their significant negative impact with a custom tune, I removed my reducer and started experiencing the true benefit of this device. The 87 Perf tune 89 octane runs much better than factory, eliminating stumbling and hesitation under heavy acceleration in all 5 gears, but some pinging was present - new spark plugs fixed that. The 93 race tune 93 octane increases throttle response and power across the RPM range and is the most fun to drive! Very satisfied with this product and Tunes for Life program to cover my next mod.
