        Son had this tuner for his 06 Mustang Gt...We no longer have that car but I would like to be able to use this tuner for my 2011 Mustang Gt, is there a way to get this done?

        • as long as the tuner is still not married to the 06 this will work on your car yes. If the tuner is still married you will need to get in contact with SCT to have the unlock it.

        Is it possible to use the tuner for my NA setup now then when I supercharge I can use the same tuner just with a new tune ofcorse.

        • Bama does not offer tunes for aftermarket supercharged applications, so you would need to look into another custom tuner once you get the supercharger installed.

        Can this tuner be used in more than one car?

        • In order to use the Bama X4/SF4 Power Flash Tuner on another vehicle it would first need to be unpaired with the original vehicle by returning it to stock.

            So I’ve got an 4.0 cai, ignition, full exhaust. Had a little more power but I wanted more. Bought this and put a stock tune. The throttle response was crazy. Then I datalogged and emailed back to bama for about a month got my custom tune and now it has a huge power difference. It easy to use and bama is helpful. I’d recommend this to anyone

            Bought to increase horsepower but seems there's a software problem that I need to contact SCT about to get resolved. tried to upload the 87 street tune and couldn't due to a 110B error code, which according to A.M. is SCT's issue and not theirs. A.M. really gets backed up with requests for tunes and issues so it takes time for them to get back to you if you have an issue. Don't know how to rate more aspects of this product if it takes so long for issues to get resolved. Hope it works as advertised if I ever get things straightened out!

            THE Bama X4/SF4 is a simple to use but powerful tuning tool.Updates via wifi quick and easy.Download custom tunes then install on car.The car did not seem to run so well, but the tuner also reads trouble codes.I had two spark plugs failing.Changed plugs erased codes, then drove car through drive cycles to allow the the cars ecu to adapt.Mashed the loud peddle and the motor pulled to the redline way faster!I did not expect as much as this unit provided.Bonus is as I further modify, Bama will supply updated tunes to compliment them.For life!I highly recommend this unit.

            Been driving about a week now. I was hesitate to just get on it right away. I wanted to let the tune settle first, but it definitely woke her up! No more bucking in first gear when it’s cold, accelerates much smoother, rev limit doesn’t exist (exaggerating around 7,500RPM), and shifting is way smoother. Speedometer is 5mph off though I would assume that has to do with the change to my rev limit, but overall feels much more powerful and controlled. And this is with a 91 Octane Race Tune. Just an FYI Race Tune isn’t unruly and all over the place. You shouldn’t have any problems daily driving with a race tune unless you’re reckless coming out of parking lots. Let’s leave the curbs for the corvette owners.

            Simply great modification

            Performing the BAMA tune upgrades was fairly simple once realizing all the current modifications required to provide for entry. I purchased my 2006 GT used more than a year ago with small upgrades, and therefore took me a little while to determine all the details included that provided the proper inputs for a proper tune. Added a CAI to the already installed long tube headers, CAT back exhaust, and 4.10 gear ratio. Once all the options were realized the folks at Americans Muscle Tuning were very helpful at providing all the needed information associated with my tuning requirements. Now my Mustang runs better than before with the new 87 tune: idles smoothly, better fuel efficiency, and better throttle response. Haven’t utilized the full 93 tune potential but cannot wait to experience the difference. Definitely recommend the tuner for anyone considering modifications to their Mustang.

            the BAMA x4 was definitely the right choice. i tuned my 2012 3.7 and got excellent results. better throttle response, almost doubled my fuel economy, and even shifts a lot more smoothly. Worth the purchase because it’s like driving a different car in a sense. The tuning team at BAMA does take a lot longer than i expected to fulfill tune requests and answer questions which was problematic for me as this is my daily driver and i was having difficulty with the tuner. only had this tune uploaded for a few days but i would highly recommend any mustang owners the bama x4 tuner.
