After loading the custom Bama Tune on a vehicle, even a bone stock, unmodified Mustang will realize noticeable gains in HP, Torque, and Fuel Economy.

Increase your mod's potential. Factory computer settings are calibrated for the original factory components. When making performance modifications, you need to recalibrate the vehicle's computer to realize the full potential that these modifications can achieve.

Free tunes for life! Every customer that purchases a tuner is enrolled in the "Free tunes for life" program. Any time that you make additional mods to your vehicle, our team of SCT certified Bama Custom Tuners will create new tunes for you.

Custom Bama Tunes specific to your vehicle. When you order a tuner, you aren't just getting a tuner - you are getting the tuner and 2 dyno-tested custom Bama tunes:

  • Performance V2 (87-93 Octane) - The Performance Tune offers a seamless blend of power, performance and drive-ability. Improving the overall driving experience of your Mustang, the Bama Performance Tune improves vehicle acceleration, increases power throughout the entire RPM and improves throttle response with revised timing, fuel, and VCT maps. Automatic equipped vehicles offer an aggressive shifting map to provide more aggressive transmission settings. This tune is suggested for the aggressive daily driver that is looking for more "get up and go".

  • Race V2 (91-93 Octane, E85, Race Fuel) - The Race Tune is designed for maximum performance and ensures the largest increase in vehicle performance. Using the highest grade of fuel available in your area is mandatory as timing, VCT, fuel, and throttle response settings are very aggressive. Automatic transmission settings implement entirely new shift points, torque converter changes and firmness settings designed for Track use.

Nitrous (91, 93, E85, Race Fuel) - Our nitrous option can be added to any of our previously mentioned tune options, but only for 91, 93, E85, or Race Fuel.

Technical Note About Fuel. Use of E85 will require larger fuel injectors such as Injector Dynamics ID1300 or Ford Racing 47lb/hr Injectors. Unleaded race fuel can also be used, but Stoichiometric points must be supplied.

Easy to load; easy to restore. Not only are the custom tunes easy to load on your vehicle, it is just as easy to restore your factory settings. When you load your custom tune on the vehicle, the tuner automatically stores your vehicle's factory settings. To return the vehicle to its factory settings, just plug the tuner back in, select the option to restore the factory settings, and you're done.

Question Resolved

What parameters will the X4/SF4 measure? This pictures show that this new tuner will measure several things on my car, but I don't see an actual list anywhere. I am looking specifically for air/fuel and boost gauges. Is there a list of what it will measure somewhere? Thanks!

CPTCO Year: 2005 Model: GT

  • The parameters that you can monitor would be determined when hooking it up to the vehicle as it will ping the computer to see what it can monitor. For a 2010 and older Mustang things like A/F would need to be monitored with an analog input and in most cases the same with boost. These can be wired into the tool to record this information into the LiveLink software or directly onto the display screen.

My friend gave me his new X4 tuner He sold his mustang and gave me the SCT/x4 (I assume its the same thing as the BAMA x4). Its never been used. Can I still get custom tunes from BAMA? Would it be free? If not what is the charge per custom tune?

    Review from Steeda Cold Air Intake (05-09 GT)


    If you're going to buy some performace parts for your 05-09 Mustang GT then buy this product. Buy this with the Bama SF3/X3 Power Flash Tuner w/ 3 Free Custom Tunes (05-10 GT). You will NOT regret it, buy them both right now. The fit was a little tight and the product requires a bit of prepparing. HUGE performance gains and it sounds super sexy. Seriously, if you dont buy this... there is something wrong with you lol.

    Review from Bama X4/SF4 Power Flash Tuner w/ 2 Custom Tunes (05-10 GT, Bullitt)


    my girl asked if it made a difference. Well I hit second and was all over the road. I asked if she noticed a difference she said she couldn't tell because she was sliding out of her seat and trying to grab the seat belt at the same time. that was just with the 87 race tune.

    *Steeda CAI*

    I just recently purchased the CAI package with the SCT X3 and could not be more satisfied. I put the intake on in 20 min. and tuned it in another 5 min., and felt a lot more torque, and felt huge hp gains at 3500 rpms+. I also feel real good pick-up accelerating in 3+4 gear.

    Review from Bama X4/SF4 Power Flash Tuner w/ 2 Custom Tunes (05-10 GT, Bullitt)

    An absolute must!

    This was my first performance mod ( I started out with a 93 performance tune) and I have to tell you I was thrilled with the performance change. Throttle response was greatly improved, she's now pulling hard in 3rd, 4th , even 5th gear. The car is also running substantially smoother while saving 2-3 miles per gallon. This mod is a no brainer. Do it!

    Excellent Mod

    I was deciding between this Cold Air intake or JLT but let me tell you it completely woke up my 06 GT (Auto). The custom tune once I loaded it up made a dramatic difference. Its basically one of those mods for the s197 GT that you say, "Ok this thing is beast"!!!!

    STEEDA massive CAI

    if your thinking about a CAI for your Stang this is deffinitly THE ONE! after you install this and just rev your Stang up for the first time itll be like the first time you heard it. you litterally hear the amount of air being engulphed into your filter by the slight whistle at first rev and through out shifts its insane. i think ill be replacing my new tires here soon already i just cant stay off the gas. it really does unleash the beast that true mustang drivers look for when considering mods... if your thinking it may be a little high priced believe me ITS WORTH IT! install was pretty easy although i have a little bit of mechanical experiance but still very simple. steeda did it right and absolutely utilized all the space under the hood for this CAI so if you have a TB spacer like myself just be aware it will take a lil squeezing and elbow grease. overall its awesome! go buy one and tune your pony up and smoke them tires.

    Review from Steeda Cold Air Intake (05-09 GT)

    Steeda outdoes the rest

    I previously had a K&N CAI kit on my car. It was a great improvement over the factory intake tube, however fell short in several areas, mainly fit and finish quality areas. That lead to me ordering this Steeda CAI kit, and I was not disappointed. The install is very simple, just take your time, follow the instructions and you will soon be in your car, loading a new tune and rolling down the road. If you have a CAI on your car now and did not save your stock airbox, you will have fitment issues because you need to re-use to rubber isolators on the bottom. I had my car dyno tuned with this, just to wring out the most power. I am now at 314 HP and 327 TRQ at the rear wheels on 91 pump gas tune that is easy to live with on the street.

    Buy it

    Ranks next to my 4:10 ring & pinon gears in regards to performance gain. I was concerned about not having a BAMA Tuner, but my Diablo Predator tuner interfaced perfectly, Vas with Diablo provided outstanding in providing the needed support. I've gained big time hp and sound, I usually outsource most my upgrades, this one I did myself, it was so every easy my wife could have done it. Would have purchased long ago had I known the Diablo Predator would suffice for the BAMA Tuner.
