    Bama Custom Tuning at AmericanMuscle. Power. Performance. Personalized. Proven
    • Power

      99-04 V6s have dyno proven gains of 10 RWHP and 10 ft-lb's of Torque or more on Bama Custom Tunes. By optimizing the air/fuel ratio and tweaking spark timing, a Bama Custom Tune is proven to squeeze out the extra horsepower Ford left on the table.

    • Performance

      Drastically enhanced throttle response and a much more aggressive throttle map will dramatically improve your Mustang's acceleration, shaving tenths off your quarter mile time while throwing you into the back of your seat every time you smash the gas. Automatic transmissions will see an even greater gain in acceleration and drivability, as the tune adjusts shift points and firmness.

    • Personalized

      For each and every Bama Tune, we ask you 19 questions about your specific Mustang, including your unique set up and intended use, in an easy to use web form. This information allows us to write an entirely custom tune just for your specific vehicle to ensure we deliver the most power and performance possible.

    • Proven

      Our Bama Custom Tunes are developed in-house on our Dynojet 224xLC chassis Dyno. Hours of research and development through street, track and dyno testing/datalogging left us with fully refined custom tunes. The Bama Performance team has exclusive access to our inventory of parts.

    On Screen Data Logging and Monitoring. With a full color LCD display, the SCT SF4/X4 Power Flash Tuner makes it EASY to read the Built-In Data Logging or Real Time Monitored Vehicle Data, view popular sensor data such as EGT, Air/Fuel Ratio or any other 0-5 Volt source.

    Easy to load; easy to restore. 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.

    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. Just send us a list of the part or parts you've added and we'll email the new tune files to 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 3 dyno-tested custom Bama tunes:

    • Street (87-93 octane) - The street tune is designed as a daily driver program that focuses on increasing mid-range power. Automatic vehicles are further enhanced by making adjustments to the transmission's shift points and firmness.

    • Performance (87-93 octane) - The Performance program is designed to add power at 3000 RPMs and higher, focusing more on the top end horsepower and all out performance driving. Timing, fuel and throttle response settings are slightly more aggressive than the street tune. This is a great track tune but also works well for daily drivers that are looking for a little more "get up and go" than the street tune. The automatic transmission settings are the same as in the street tune.

    • Race (91 - 93 octane) - The race tune will ensure the largest increase in vehicle performance. Using the highest grade of fuel available in your area is mandatory. This file is designed for "Race Use Only", as the timing, fuel, and throttle response settings are very aggressive. It is so aggressive that we do not recommend it for daily driving as it may cause your vehicle to try to jump out from a stop and easily spin the tires. On automatics, we implement entirely new shift points and firmness settings to further enhance the all-out performance of the vehicle.

    Nitrous (91-unleaded race gas) - Our nitrous option can be added to any of our previously mentioned tune options, but only for 91-octane unleaded fuel.

    **NOTE: Programming custom tunes may take 2-3 business days plus applicable shipping time. We recommend ordering other products separately to avoid delay. Some heavily modified cars are not tunable with a mail order tune. Click for details.

    Hello Is this tuner Legal for CA use? Thank you


    • The Bama X4/SF4 Power Flash Tuner w/ 3 Custom Tunes would be legal in CA.

    I am wondering if I can use this tuner on multiple different vehicles. For example, I have a 2002 V6 Mustang manual, with minor mods (intake, exhaust, etc). Would I be able to tune my car and than use the same tuner and tune my brothers 2007 V6 Automatic with similar mods?


    • When you tune a car with your BAMA tuner, the tuner will marry to that vehicle, and will only be compatible with that vehicle until it is returned to stock and unmarried from that vehicle. You would not be able to tune two different Mustangs with one tuner.

    Does this item have money back guarantee? This tuner seems to be pretty polarizing for the reviewers so it would make the decision to buy easy knowing you weren't out $400 if it doesn't perform as advertised...


    • The Bama X4/SF4 Power Flash Tuner w/ 3 Custom Tunes would not be returnable as they are custom to your application. If you run into any troubles Bama Performance is more then happy to help find and correct the issue.

      Like I said this products works. Period. It's a simple plug and download operation taking minutes at longest. Instant proformance gain! If you think the standard 3.8L v6 is a slouch of an engine? this flasher unlocks the engine without damaging the modules. Safe easy to use product. Paired with an intake and exhaust and you easy chirp into 2nd, without any previous mods and just the flasher I still wouldn't doubt you'd get some tire chirp shifting into 2nd.

      The custom tunes work amazing! I was having issues when I swapped from an automatic to a 5 speed, but once I uploaded the custom tune, the car functioned and ran like stock. But not only did the tunes fix my car, but made it pick up a few extra hp as well. There's definitely a night and day difference with the 93 octane tune. It feels a lot faster, especially with the 5 speed, and the only other mods I have is a cat back and cai.

      This thing is amazing. Already had a KandN CAI, MSD coil pack and plug wires, BBK shorty headers, off-road Xpype, and flowmaster duals and now my little 6'er flies down the road! The street and performance tunes kinda feel the same but the race tune is crazy. Very glad I finally bought this and highly recommend to others!

      Worth every cent

      After a week of impatient waiting my SCT tuner finally arrived, programming was easy and man talk about bang for your buck!!!! I purchased it because I have a rear end with 4.10 gears in it but even without them being installed yet this little magic wand really brings a basic v6 to life. Passing is much smoother with more gettyup shift firmness if beautiful and throttle response is awesome. Makes me want to kick myself for waiting a year because I was unsure of what it can do. If you're thinking about buying one stop thinking and buy it..... Well worth the money.

      Nothing describes my first impression better than the word WOW...

      I totally underestimated the difference this would make. Before buying this I did a lot of research and watched a ton of videos to make sure this mod would actually be worth it but honestly no video does this thing justice. It increased the power very noticeably but I think the most impressive part is that on my auto transmission the shifting has become smooth as butter and really really fast, my car no longer hesitates before shifting at all. Thanks again AM for another amazing product, I'll definitely be back soon for more mods!

      You get what you pay for!!!

      Dollar for dollar this is the best mod for your Mustang. It is easy to install, and does Exactly what it should. Customer and tech service are exceptional. This mod made my V6 more responsive throughout the power curve and smoother overall. Why pay more for a V8 when you can have this level of performance from a V6? I have installed a CAI, an X-PIPE, and cat back Flowmaster duals. The Bama tune brought it all together! Virgil W. in Alabama

      04/V6 GT KILLER

      First of all, I want to start with WOW… I mean honestly this modification for my car has been the best thing I have done for my Stang. My car woke up like a beast. Just like everyone I have read and seen the review and videos lots of times before buying the Bama Tuner. Un like other bad comments about the Bama Tuner my car is heavy modified. My 2004 Oxford-white 40th anniversary V6 is equipped with: JBA Headers, True Dual Cats with Magna Flows and 3” Stainless steel tips, MSD Performance coil, 10mm Spark plug Livewires, NGK iridium IX Performance Spark plugs, BBK Throttle Body and BBK CAI. Amongst other heavy mods to my 3.9L engine. And now finally a Bama Tune running in Performance at 91 octane. Over all giving my Stang a monster power performance. Bama and American Muscle you guys are the greatest thank you for existing and for your five-star customer service. Most of the performance parts on my car have been bought here at AM.

      It's great, I pluged it in and answered some questions and BAM...A I was ready to rock and roll, my stang is an automatic and it no longer hesitates to shift when it hits readline, it's so smooth that it's like a new car! Steping on it won't ruin your mileage eather, I just got though my first tank and I gave it a ton of petal when going around town STILL got 23 at the pump! Before I was close to 17! If you are like I was (looking at the price and on the fence) definetly get it as now it throws me into the back seat at the stop signs!

      Bama x4/sf4 power flash tuner

      This tuner really woke up my mustang. It gave my v6 a little more power, and made it funner to drive. It's a pretty fair price to pay, considering all the things that it's able to do. If your sitting on the fence like I was, don't think about it, just buy it. P.S. The race tune is very responsive, and may cause your tires to break loose. So be careful infront of cops, because they will pull you over for doing "BURNOUTS".
