Review & Installation Video

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.

if im using this tuner on my auto 2013 gt what happens when i go into sports mode? i like how it holds my rpms a bit higher and was wondering if it would still work or not

Jck10

  • The tune will still be in the car and it will keep the changes as far as performance gains to the engine go. However if you have an automatic transmission, and you switch it from the normal drive mode to sport mode, the other modes will keep their tine but it will revert to the transmission settings of the specific mode you are in. So if you are in sport mode, it will have the shift points from that specific mode and not our transmission settings.

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.

DamoCT

  • 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.

    Exceeded all expectations

    I put in an Airaid CAI 2 years ago but didn't do any tuning; at the time I didn't have the interest. Plus, I didn't want to lay out that much money at once. However, recently the tuning bug hit me and I've been itching to tune my GT. I was all set to order the X3 but I saw the X4 had just been released and I figured for the couple extra bucks, there was no question to get the X4. The screen is very nice and crisp to look at. It is plenty bright whether you are in the dark or in direct sunlight. The wireless feature is quite handy as a lot of times, the USB cable isn't right there when you need it. The interface is very user-friendly and intuitive. I was sure to update the unit's firmware right away as that was recommended upon first opening the box and examining the contents. As for the tunes, I am floored by the amount the GT has woken up. I loaded the 93 Performance tune and just night and day difference over stock. I immediately noticed just pulling out of my street! Once I got on the highway, well all bets were off and in a split second I was over 80mph. Even my fiance was impressed by the difference! Once again, AM was great in answering my email questions and getting my X4 to me fast and Bama did an awesome job with my tunes. Thanks so much and I will no doubt be recommending and praising both of you.

    SCT X4 Programmer

    I was looking to add some extra muscle to my GT and bought the X4 as soon as it became available. I had read all the reviews I could find and even talked to the folks at SCT. The new X4 is by far the best programmer to date. Its ease of use and the new wifi capability made installing firmware updates a breeze. It can also be mounted in the car and coupled with the data logging ability, provides a easy to see read out. I would highly recommend this to anyone looking for a small, light, and powerful programmer.

    Impressive HP Gains and Ease of Use with Bama X4/SF4 Power Flash Tuner

    You can't beat free tunes for life and with the addition of the Steeda Cold Air Intake the "seat of pants" increase of performce was amazing. The tunes really woke up my 5.0 6-speed and I couldn't be more pleased with the results and the performance gains. I have the Track Pack with 3:73 gears and it feels like I gained substantial HP and feels like a different more powerful engine. I'm enjoying all the features of the new X4/SF4 Tuner and it's ease of use.

Load the Bama Custom Tunes and you will definitely feel the difference on the butt dyno. I know the 91R Cam tune really let my car Giddy Up Go and the idle just sounds like good old American Muscle .This tuner will really wake your pony up and let it out of the stable, it's a great place to start if you want to get a little more out of your mustang for a decent price and let's face it you pretty much need one of these for most major bolt ons so why not start here .

    Don't wait, Instant results!

    I had been putting off getting a tuner for a while because I wasn't sure I needed one. Boy was I wrong! In more ways than one. I didn't think I needed it because my 2012 GT is a daily driver, not a race car. But I enjoy spirited driving, and performance on demand. I have a Flowmaster catback and Roush CAI - so mildly modded and didn't "require" a tune. After a lot of research I decided it was time. I did a lot of researching online, and with tuners, everyone has an opinion. Well I gave Bama a try, because of the deal they offer through American Muscle. Tuner 2 tunes and tunes for life for $399. I figured I might as well give it a try. And I have to say I was very pleased! I filled out the form, telling BAMA what mods I have, and what I was looking for. A few days later, it arrived in the mail. The WIFI was easy to hook up, and downloaded updates and tunes in minutes. Loading the tunes on to the car was easy, and I felt an the difference immediately! I'm an automatic, and I've always felt the stock shift points were early, - this tune fixed that! Now it shifts later, letting you get into the power band. I recommend having them turn off "Skip Shift." The car sounds better, and performs better. AND as an added bonus I'm getting 2 mpg better! on a 93 tune! (got 18mpg before, getting 20mpg now) - They offer data logging and revisions - but so far I don't think I need any. Free tunes for life makes me feel good about adding mods down the road. So far, i've only tried the performance tune - I'll load the race tune when I get a chance to really open her up, and report back. For less than $400 bucks - it's really the most HP / dollar you can get.

    Bama Power Flash Tuner

    I was looking for a little extra power and the Bama tuner did exactly that. I have an auto transmission and the tunes firmed up the shifts and optimized the shift points. For the money, you can't go wrong. I run the performance 93 tune on the road since this is my daily driver and flash the race 93 tune to the ecu when at the track. All my buddies were surprised that my auto convertible with 3.15 rear end ran a 12.8 at 111mph. I still have a few tenths left to shave off! Awesome tuner.

    Seems great

    I have a 2013 muustang gt with the track pack option. First of all the tuner itself seems to do a great job and adds noticeable power. But I have only used the performance tune so far not the race tune and I'm sure the race tune is way more noticeable. My only complaint is bama recommends to update the tuner before you even take it out to your car. Can't they do this from the factory? Obviously you need to be able to use the software and connect it to your computer at some point in time anyway but it would have been nice. Throttle response has improved as well. You may have a few headaches getting the software to recognize the tuner on your computer but you will get through it. Bottom line, this is a great tuner for the money.

    Waking up the coyote

    I never imagined ford left so much of the 5.0 back in the factory. My biggest concern was the throttle lag . How annoying to tromp on the gas and feel a1second delay; Using the performance tune throttle lag is GONE . Now it's just a matter of how much of a burn out I want to do. My Stang is an automatic so shift points are also different NO LAG. Over all the power anda performance gains are really impressive. Highly recommend, thanks AM

Haha but overall great tunerring aside from that crazy issue that it's so sensitive to voltage it needs to update ur car with new tune.

    What are you waiting for?

    I have a 13 GT convertible with automatic transmission. It is completely stock. When I got it, I loved the power but when very underwhelmed by the soft shifting. I figured I'd try a tune, even though my car isn't modded, to hopefully firm up the shifts. I ordered the X4 and two tubes on Tuesday night, and received the tuner with tunes installed on Friday. The tuner itself is small and light. As long as you have a wifi connection, you can update it without plugging it into your computer. This was very convenient. Loading the tunes into your car is easy, too. Simply plug the X4 into your OBDII port and follow the onscreen instructions. It took about 15 minutes total. Running the 93 Race tune, I was immediately impressed by the much improved throttle response and significantly firmer shifts. Now, with the stock pirellis and 3.15 gears I spin the tires all the way through first gear even without opening it up all the way. If you're on the fence about this, take it from me. You won't be disappointed.
