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.

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.

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?

Crashin

  • 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.

Will the tuner have the be plugged in my car at all times?

  • This would not need to stay plugged in your mustang. You just download the tune unplug it and got. The only time it would need to stay plugged in is if you need to data log (gather information) the car

I just watched the video and it says 10HP 10TQ gain. But I only see 6HP gain -2TQ lost. Are the numbers correct or maybe video editing error?

Ali82

  • The video displays the peak numbers, which our math is correct, there was a 6hp gain in the max power achieved and a 2lbft drop. The 10hp and 10 ftlb gains are across the curve, or below the peak power produced. In the video, peak torque production occurred at 3250rpm which is where the 2 lb-ft loss occurred, and torque stayed similar until around 4250rpm, where with the tune, the torque produced stayed higher than without the tune, through the redline. Similarly, power production continued much higher into the RPM range than with the stock tune. The reasoning for this is that in performance applications, higher rpm power is favored, as this is where the car will remain for longer periods of time.

If i get the tuner, do i need a performance chip too or will i see gains with the tuner alone?

GOAT

  • Hello! You would not need a performance chip to use in conjunction with this tuner. In essence, what a performance chip does, is what this tuner does, but the tuner is tailored to your specific vehicle instead of being an off the shelf tune.

    I have an 04 3.9l 5 speed and have had the x4 for a little over a month and you can really feel the difference. Running the 91 race tune right now and is probably my favorite. Got a little more power down low and really wakes up around 3k rpms. Not disappointed!

    Excellent!!!

    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.

    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.

    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.

    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

    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.

    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
