Street Tune: Designed as a daily driver program that focuses in on increasing mid-range power.

Performance Tune: This tune adds power at 3000 RPMs and higher, focusing more on the top end HP and all out performance driving.

    • Hello Mike, your custom tunes should have been loaded on the tuner before being shipped out to you unless you requested the tuner be shipped out without them. In either case, you would have received a tune survey email for you to fill out. If you did not complete a survey and feel that you have received the tuner without custom tunes please contact Bama by calling in, emailing at, or you can request tunes by following the link below.

    Hello. Does this tuner provide real time statistics on screen such as HP, torque, quarter mile times? Or does it just show diagnostic information? Thanks!


    • This tuner will show the gauges in real time when you datalog. Unfortunately, there is no setting to see them separately. So when you datalog, you will be able to see your current RPMs, Boost PSI, Coolant Temp, Voltage, and so on.

      Easy to Use

      The X4 is very easy to use. I have a blower installed and several other upgrades. The only issue I ran into was using a PLX DM-6 wideband O2 kit/guage. Getting the datalog squared away on this was a big headache. Other than that, the car runs strong and steady now. I was having a pretty bad surge when cruising at highway speeds with the cruise control set. The surging has gone away thanks to the tune. Looking forward to getting on a dyno and really seeing how the tune has helped.

      Been waiting for this one for a while...

      I wanted a Tuner that would take care of my S197 then later move to my S550 once the warranty was up, and this is it. Its Pre-loaded with basic tunes that liven up the car, has an ability out of the box to adjust for many of the basic CAIs and other popular settings. I noticed that once I loaded the pre-loaded tune it woke up my S197 Automatic GT and made it feel more like the car I wanted, but when I got the Bama tune 2 days later the shifting points were more aggressive and response seems more aggressive than the SCT Pre-loaded tunes. Launching of the GT is more on par on how my Ecoboost feels now on throttle response, gone is the wait for the system to think about doing stuff. I have lowered and beefed up my suspension which after the tune is a must... Otherwise if you dont, the extra power will turn you into a Youtube highlight reel of a mustang leaving cars and coffee into a curb. I was never able to chirp 2 and 3 gear till after the tune. the RPM Shift points are more on par with a Manual..

      Best programmer by far

      This thing is freaking awesome!! Definitely exceeded my expectations.. I have a 2015 mustang gt and you can definitely tell it purked it up.. Way more low end throttle response and of course big power difference you can definitely feel it.. Would recommend this to anyone I've owned alot of different programmers this is by far my most favorite and very easy to use!

      Was ok...

      Took about 8 wholes days to receive. Tune was preloaded so another 3 days before that was emailed. After the 89tune was uploaded the car wouldn't shift into 2nd. Killing all performance. The 91tune was perfect with the flaw that it revs so high I have to force shift using paddles even when only doing 30mph on streets. Makes me have to have my hands on paddles. Maybe it's just an automatic issue but I won't be buy this again. Save your money and buy the Lund racing tunes. They have never left me upset.

      First off, there is a difference you will notice in the overall feel and driveability, I am using a 87 street tune and 4 things are clearly apparent, higher idle, uses all 6 gears and holds gear longer ( shift changes are worth the price alone), throttle response is very sharp almost snappy, power throughout the range has no flat spots. What it did not do in this tune was raise the rev limiter or max shift point, bark off 1 to 2 or 2 to 3 shifts, drop more than one gear when you mash the throttle or light the tires up out of the hole, you still need to throttle brake and shift manually to get max potential... not easy with the stupid button on the shifter... but that's ford not Bama... 5 stars on the product and the entire purchase install process....

      I had a few modifications to my car. Cai,gears,exhaust and there was a difference but was not quite all it could be. With this tuner and the Bama tunes made those parts work together and now I have a completely different animal on my hands to the point of relearning how to drive it.

      It does it's job.

      It took care of my rear O2 sensor CEL and made for a much more steady power curve. My only issue was that they forgot to send me the USB and obd2 cables and I had to wait an additional week before I could use it. The tuner itself works as I had expected it to, its not a waste of money.

      Great Tuner, not Tunes

      The Tuner itself is fine. Does what it's suppoised to do. But the Bama tunes provided for my Mach 1 are horrible so far. In a back and forth process where after data logging the next tune was just the same . Greer. Taking a break out of frustration and back to stock so I can drive my car now but I'll be requesting new tunes again that hopefully I can use. .
