    Review & Installation Video

    Justin: Hi everyone, Justin with 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, 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

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

      05-10 GTs have dyno proven gains of 17 RWHP and 18 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 Ford left on the table.

      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.

        I have a 2008 mustang GT that has a Bama custom tuning member plate in it. I don't have the tuner, or any reliable information on the modifications made to the car before I bought it. I will be purchasing your tuner but was wondering if I provided the details on the plate and Vin number could you work out a stock cam tune and the last known tune for the cams that are in it. Thanks

        • We would recommend contacting BAMA directly to see what information may be available from the previous tunes, and what they may or may not be able to do with any information they can locate.

        with the 93 octane tune will I have to run 93 octane gas?

        • Yes, with a 93 octane tune with the Bama X4/SF4 Power Flash Tuner you would need to run 93 octane. If you are worried about not being able to find 93 octane you can request a 91 octane tune and run 93 when you can find it. You can run a higher octane but never lower.

        I purchased this tuner a while ago. I am getting ready to change to tires that are smaller in diameter. I couldn't find the function to calibrate the speedometer to the new tire size. Could you tell me where that is? Thanks!

        • You will need to get a tune update from Bama Performance for the tire change. This will be a free update you just need to get in contact with Bama Performance.

            Interesting Experience

            Bought this little monster for my 2006 GT' with the 8 cylinder, 4.6 engine and about 100,000 miles. My advice is as follows: A). Make sure your batter is good shape and holding a strong charge. B). Go to the SCT site and download their proprietary software so that you can easily load times from your email and ensure that the software on your device is up to date. C). Read the instruction manual...even if you are well-versed in car electronics. D). Make sure that all of your ground wires are secure and free of corrosion. I had loaded the 87 Performance Tune onto the SCT scanner, loaded the tune into my would go through up to the point of confirmation and an error message said the tune was not complete. Finally, it loaded on the second attempt so, I merrily went off thinking all was fine....I got 1/4 mile from my house, but the breaks....and my Mustang goes lame....I managed to give it a rest while I ate dinner....went outside to start the car and it revved up to 1500 RPM....crashed to "0" and did the same thing for about 5 minutes before I turned it off. Of course, all of the mean and nasty idiot lights were, I had it towed to my dealership the next day. They were concerned that the ECM or PCM were fried.... They reloaded the stock tune and after performing some additional diagnostic work, they found that the nuts that hold the ground wires from the ECM were corroded...and that's where the problem was. They reloaded the 87 Performance Tune...took the Mustang for a run and say everything is fine. I am out about $600 for the diagnostics and the other work they did (I am going to pick up the car this afternoon and run it through its paces before I go back home with it. Of course, it could have been a lot worse if the ECM was fried....ouch..(but, that did not happen). I will keep everyone posted on how the Mustang handles this afternoon on its maiden voyage onto the highways and back roads this afternoon. Joe in Minneapolis

            Not quite plug and play as they say. You need to up date to a computer or WiFi first. Didn’t come with 2 customs times. Haven’t notice any real gains. Could only show 2 gauges on the gauge function. Never bought a tuner before probably wouldn’t buy another.

            A must for bolt-ons

            I recently installed my Roush CAI and exhaust, and GMS throttle body without a tune for comparison and although the bolt-ons worked magic on my S197, having the tuner with a BAMA performance tune enhanced their capabilities. The device is extremely easy to use. As you get performance parts, simply request a tune and within days, you’ll open up added performance features from your bolt-ons.

            Good stuff

            I’m happy with it. At first not so much with the pre loaded tune I put on my car that camewith the device. Car was running a little funny but a few days later when my airaid race CAI came and I up loaded my custome tune to it. It was by far much better!! Car put down the power a lot better and more smoothly. Over stock and preloads. I was also running a borla cat back! Car seemed a lot louder befor the tunes, but after not so much but It screams in the higher rpms a little more than befor atleast. So that’s still nice. But all in all car runs better and puts down the power better for sure!

            Bama X4 Tuner

            The Bama X4 worked as advertised, first tune I installed fixed my speedo issues due to the 4.10 Gears I installed and opened up alot of new power and quicker smoother shifting with my automatic. The tuner is easy to navigate and use, I also like the Wifi feature for new device updates. Money well spent in my opinion. Cant wait to do another mod to my 08 GT and have my next free Tune sent out from Bama.

            After installing the tuner now my car wont start ... now I have to pay ford so they can reflash my ecu and hopefully the device didn't damage my ecu .... so $400 went to the trash I'm very disappointed with this sct device
