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.

Diagnostics. The SF4/X4 Power Flash Tuner can also be used as a diagnostic code reader. Save yourself hundreds of dollars each year by reading and clearing your own trouble codes rather than paying a dealer to do the same. Its as easy as a few simple steps.

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!

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.

Replacing SF3/X3 tuner? Just kind of concerned because i recently bought the SF3/X3 tuner and this is coming out already. It states on the product info that the new SF4/X4 is replacing the previous version. Does that mean that the SF3/X3 will no longer be useful as far as getting new updated tunes?

    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

    Bama X4 flash tuner for my 3.8L V6

    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.

    MUST-DO-MOD for my mustang

    This turned my 2004 V6 into a monster compared to what it drove like before. This saved my pride - bought mustang in average condition, my wife thought it was a below-average decision. Now she loves it. A man has to do what a man has to do and getting one of these is what you have to do.

    Lot of money but great performance gains!

    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".

    Best thing to bring moderate mods together.

    My car has CAI, true dual exhaust, and bbk headers these mods were great on my car at first but after I put in the 87 performance tune my acceleration from 0-60 increased by nearly a second and a half. Now in a v6 that's quite a bit. I love the acceleration and this was definitely worth the purchase. My advice is buy it and you'll love it.

    My take on the bama tuner

    When I first got this tuner I slid Into my mustang all exited because I had finally gotten something had been so hesitant to buy before. The first tune I put I to my stang was the performance tune and right away I could tell a big diffrence. The shift firmness was nice and aggresive and over all pretty awsome. It really woke my ride of up with beter gas mileage to boot. The only thing I wish was a little beter was the price, because that kept me on the fence about it for two weeks. Other than that I'm more than happy for buying it. I can finally run the gt"s down now
