    Review & Installation Video

    Justin: Hey, guys. Justin with, 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 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.

    I have a 2013 Boss 302 with the red TracKey. I really like the TracKey functions especially the lopey idle. How will this tuner work for me? Will I still be able to keep the lopey idle and make gains like the GTs do? Does Bama already have Boss 302 specific tunes created and verified on the dyno? Are there any specific Boss 302 parts you would recommend with this tuner? Would a different tuner be better for my application? Currently the Boss 302 is stock. Thank you!


    • You can definitely use the Bama X4/SF4 Power Flash Tuner with your 2013 BOSS 302 with the TracKey! BAMA can generate tunes for your application without changing any setting with your TracKey including the loopy idle. If you decide to go with a tuner, custom tunes can be generated but you would have to use your regular key when utilizing the tune. If you'd like to use the Red TracKey, you would need to flash your computer back to factory settings and then use the TracKey to be able to use that function. There are no specific items but we would suggest performance parts like a Cold Air Intake or an exhaust to boost your performance.

    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


    • 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.

      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.

      Threw away $400

      First off let me say the techs who tried to help me were great. The tuner itself is fine but the Bama tunes are hit or miss and are cookie cutter tunes written on a test mule and may not work on your particular car. I went back and forth for close to four months with bama performance trying to get the tunes to work with my 2013 GT with no luck. I ended up having to go to injected engineering in kennesaw GA to get my car straighten out from the mess the bama tune did on my ecu. I ended up spending a full day of missed work and $800 on a custom dyno tune fixing what a $400 tuner caused to my car. Lots of guys claim they had good results with this tuner but I didn't and have heard a lot of others having issues as well. It may work for you but realize there's a good chance it may not and you will be stuck with a $400 paper weight like me.

      At first i was very unsure of getting a tuner 1. because my car doesn't even have 5 thousand miles and 2. because well would it really help my performance that much for the price? after some time I caved and ordered it. A birthday present to myself. best decision I could have made. took maybe 15 minutes to do everything. took it out right after, i noticed a difference immediately. Then when I took it out on a back road to see what changed through the power band it was night and day. getting this product is worth every penny!

      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.

      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.

      Good Tuner, Great Support!

      Received my X4 fast due to quick shipping from American Muscle. The tunes were just as I had ordered but my speedometer was off by 10mph. An email to Bama Performance/American Muscle had a new tune out to me the same day to correct the problem, which turned out to be on my end and not the tune. I purchased my '14 GT used with 5k miles on it and have never seen a sticker or build sheet for it but it turns out that it was ordered with 3.73 gears instead of the factory default 3.31's. If anyone else has a problem with their speedometer on a 13/14 model, inside the driver's door, you will find a two-letter axle code: BB - 3.73 ratio CC - 2.73 ratio DD - 3.55 ratio GG - 3.31 ratio YY - 3.15 ratio Thanks again to American Muscle for sending me a tune that allowed me to find my issue!

      Giddy Up Go

      The new S4 is great so easy to use, fast, and is a lot better looking than the previous x3 model by a mile. 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 .

      I really didn't want to be that guy because I love this site, it's more of an issue with Bama support rather than AM, and I thought how could I go wrong with all of these great reviews. However, I uploaded my 93 performance tune on my 14 GT and ever since then, I have been having minor problems, which I expected to an extent, as a tune is very detailed and specific to each car. I can notice the increase in HP and TQ. As far as throttle response and power distribution throughout the RPMs, it varies. When I am at idle and press the gas to give it a little rev, it is a hit or miss whether it will actually rev as expected or nearly bog out. Same goes for when I press in the clutch at any speed and hit the gas to rev match, it might rev as expected or bog out and cause a huge engine brake from downshifting without matching the revs. That is the biggest problem. While in a gear and staying in it, the throttle response is certainly better than stock. When I contacted Bama support, I received a quick reply on a Saturday(awesome I thought) with instructions on how to data log, which I understood had to be done and I completed and sent the following Monday. However, since then I have been trying to send the file, and ready to do whatever I need to do to resolve these issues. Unfortunately, I am only receiving 1 maybe 2 responses a DAY trying to transmit this data log, confirm they received, get updates, feedback, etc., which is very frustrating for car guys just trying to fix the issues ASAP. I hope Bama will be able to fix these issues so i can change this review, but until then I have to say, I am disappointed as this is one of my first performance mods I have purchased for my GT.

      It's Alive!!!!

      Completely awakens the beast! Throttle response is 10x better and a significant power increase you can feel through entire rpm band! I pared it with an airaid CAI and couldn't be happier!! Still haven't tried the race tune but I'm told most ppl use it for daily driving, and that's where the most significant power gains are at..

      Why did I wait!

      I absolutely love my tuner,shouldn't have waited but I figured I should get the rear to hook before making any more power. This is night and day,to much fun for an old guy like me. I have already taken it to the street and it is deadly, love it. Can't wait for the next stages of my build. Thanx tons

      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. Who would have thought it was so quick and easy to order Tunes for different octane ratings and receive them in an email so fast....I'm very happy with this product.

      Installation is a breeze!!

      The tuner was extremely easy to install on my car. Just plug into the OBD to choose your tune and allow it to download and enjoy the performance gain.

      I just wanna go FAST!!

      If you don't already have your mustang tuned, you're missing the boat. This is the easiest thing you can do to get an immediate boost of rubber burning excitement! Do it, you'll thank me.
