Justin: Hey, guys. Justin with AmericanMuscle.com, here to talk about the benefits of using the Bama X4 Flash Tuner, loaded with the new custom Bama V2 Tunes on your Coyote powered '11 to '14 GT.Now, here with me today, Paul Meister from the Bama Performance Team. He's going to talk a little bit more about what the average Coyote owner can expect when uploading a tune to their GT. Paul?Paul: What you can expect when uploading your tune to your '11 to '14 Mustang GT is a complete remap electronic throttle calibration for improved throttle response. For the automatic owners, it's a complete redesign of the shifting characteristics from shift points, torque converter lock and unlock, fan setting changes, fuel map changes, spark map changes. And of course, a refocus on the twin independent and variable cam for improved drive-ability and maximum performance.Justin: Absolutely. With the new Bama V2 Tunes, we're talking about a performance, and we're also talking about a race tune. Can you explain the difference?Paul: Correct. Our Performance V2 Tune is really designed for that aggressive daily driver. It offers a seamless blend of performance and drive-ability. And we do that with a remap ETC; electronic throttle calibration. The automatic guys get a completely revised shift schedule, torque converter changes, and again, some of the twin independent variable cam stuff as well, that we spoke about.The Race V2 Tune is designed for just that; race use only. We pretty much disable all the torque management. It's designed to shift really aggressively for the automatic guys, and just deliver everything that's left on the table from the vehicle.Justin: Yeah, and guys, don't forget, with Bama's "Free Tunes For Life," as your car's modifications grow, Paul and his team at Bama Performance will write a new tune for each and every mod so you can get the most out of your set-up.Now guys, that's going to do it for now. Paul's going to basically translate what he just said in the dyno numbers shortly when we run our 2012 GT behind me. But in the meantime, Paul's going to get out of here. We're going to talk a little bit more about what you can expect with the X4 tuner itself.As for the actual Bama SF4 tuner itself, well, as you can see, it's a pretty sleek, compact and modern design but with a very large, easy to read, full color LCD display. Now, some of the features with this full color display include a landscape mode, meaning you can turn it sideways, just like a lot of smartphones out there, for a completely different view.You can also choose different colors and themes available through a menu. And you can also go ahead and select a power-saving auto-dim feature to use while the tuner's plugged in but not in use.So, why the larger screen? Well, the Bama SF4 does feature on-screen gauges and data logging similar to what you'd find with more expensive models like the SCT Livewire or even the ITSX, for instance. These screen layouts are fully customizable and can display up to eight different values at one time, including boosts, air fuel ratio, coolant temp and intake air temperature, just to name a few. And by the way, you can data log these just with a simple touch of a button.Other features with the SF4 do include built-in WiFi which is a nice little touch and allows you to take care of those future firmware updates wirelessly.Now, the tuner does feature dual analog inputs and a removable power cord, making storage in a glove box or armrest that much easier. The tuner does still hold 10 tunes at one time and is still capable of reading and clearing those diagnostic codes just like any other tuner available out there on the market today.Finally, guys, if you do have any more questions about the SF4 tuner itself, please head back to the product page at AmericanMuscle.com where you can read up on some more details in addition to some customer reviews.Now, before we show you just how much power you can expect on your '11 to '14 GT using a custom Bama V2 Tune, I just wanted to walk you guys through the actual process of uploading the tune using your Bama Performance X4 Flash Tuner, and then we'll go ahead and make our Dyno pull here with our 2012 GT and show you guys the results.To start, you're going to want to locate your car's OBD-II port, which on the '11 to '14 Ford Mustang GTs is located on the lower portion of the dash here. So, go ahead and plug your tuner in and wait for it to power on. Navigate to your performance or race tune. Select the tune you wish to upload. And then just follow the detailed instructions listed on the screen here.Of course, if you guys have any trouble whatsoever during this process, you can always reach out to a Bama Tuning Expert. They're always standing by, ready to help you guys out.With our baseline run already in the books and the tuneup loaded, Paul's going to hop in the car and make another hit here on the Dynojet and see what kind of numbers you can expect with your GT.Our baseline run using our stock 2012 GT gave us 365 horsepower and 343 pound/feet of torque at the rear wheels. With the Bama V2 93 race tuneup loaded, the car is now making 397 horsepower and 382 pound/feet of torque. That gives us a peak gain of 32 horsepower over those baseline numbers, and gains of as much as 50 horsepower and 47 pound/feet of torque throughout the curve.The Bama X4 tuner loaded with the new custom Bama V2 Performance and Race Tune is a great way to make the most out of your stock or modified Ford Mustang GT, and is no doubt one of the easier mods you will ever tackle with your ride.For more tuning information with your Mustang, be sure to subscribe to our YouTube channel, and pick up your Bama X4 Combo right here at AmericanMuscle.com.
