    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

      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.

    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 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.

      IT’S ALIVE!!!!

      Finally picked up a Bama Tuner! When you order you will be asked a series of questions about your Mustang that relate to the types of mods that you currently have on the car, each question has a drop down box that lets you choose yours. Once that form is complete you submit it and within a few minutes I had an email from the guy that put the tune together stating that it will be on my tuner when it arrives. The email also has instructions with the steps you should follow before connecting it to your car, which include downloading the software for the device to your Home PC and then connect your tuner to your PC to make sure your tuner has the latest software update. My car only has a 4:10 gearset and a different tire size, which is asked on the form. With the gear set the car has a lot more low end pull and it’s fun on the street but since the tune was put in the car seems to breath much better. My apologies for the long post but get off the fence and buy a tuner even if your car is stock, it makes a huge difference. Tunes for life and I just ordered my next tune which i received via email within minutes because I’ve got a CAI coming. Hope this helps!

      More than Satisfied

      The Bama Tuner Cleared my check engine light code, I immediately felt the car was lighter (moving faster) when I programmed the custom race tune on it for my bolt on mods. My gas mileage went from 18.7 to 19.1mpg . Amazing product at a respectable price

      Worth every penny

      Installed a JLT Series 3 and race 93 tune and it feels like a different car. Pulls hard and grabs 2nd and drive. I also will note that I had a hesitation off the line that was so bad that I thought I was having a transmission problem. That all went away with the tune.

      Good mod, no TCS/TPMS disabling

      Overall, it's a nice upgrade. The 87 tune mostly just feels like a little quicker throttle response, the 91 tune does feel like a little more power and I was happy with it on the track. My only complaint is this tuner can't disable the annoying TCS and TPMS systems. Without these I'm not sure it's worth $400, but still a good mod.

      Bama Released the gorilla in the cage, its amazing

      The tunes that I have received from BAMA tuning are amazing and that is putting it lightly. With each improvement in performance parts I ask BAMA for new tunes and they are very very good about quick turn around, and the tunes work perfectly. The last race tune I received was a real thrill to try out, I love getting on the interstate and running thru the gears, the car performs like a true muscle car. Can't wait to get my next performance upgrade in parts so I can get more tunes to enjoy the horsepower gains. Thank you BAMA Tuning

      Makes the car run like it was meant to

      I haven't had a chance to run the 93 octane race tune yet because that stuff is way too expensive right now, so I can say much on the power gain, but I put the 87 performance tune on and it makes the car run like it came out of the factory with these parts already on it. Definitely notice some low end torque with the 87 tune. Can't wait to try the 93

      I now run the 91 Race tune on my 08 GT. At first I could not run it due to detonation problems. I tried a lot of different settings on the tuner but no luck. After thinking about issues that I had in the past with det on small turbo motors I decided to close up the spark plug gap. Bingo! No issues at all now and it pulls great.
