  • Power

    05-10 V6s have dyno proven gains of 16 RWHP and 21 ft-lb's of Torque or more on Bama Custom Tunes. By adding more fuel, optimizing the air/fuel ratio and tweaking variable cam timing, a Bama Custom Tune is proven to squeeze out the extra horsepower that 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

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 3-4 business days. We recommend ordering other products separately to avoid delay. Some heavily modified cars are not tunable with a mail order tune. Click for details.

Remove the REV Limitation? Are there option in this tuner to remove the REV Limiter on my Mustang?

KyleE Year: 2007 Model: V6

  • No, this is not something that you would be able to do or that we would do within the tune. Removing the rev limiter can lead to potential engine damage that would destroy the engine. We do however raise it a few hundred RPM's within the tunes.

Can this withstand heat? I was planning on leaving this in my car so I could change the tune without having to go all the way back home, but I'm afraid of ruining it with the Arizona heat. Especially with it being a black mustang.

GLFWNG Year: 2007 Model: V6

  • These devices can withstand some heat but I would suggest if you are leaving it in the Mustang to not have it in direct sunlight. These devices, like any electronic, can overheat. If you store it in your trunk you should be fine but if you go to load up a tune and it is very hot to the touch you may want to let it cool off a bit before loading the files.

    Woke up my 2007 V6 4.0

    Ordered the Tuner listing my current mods, came to me nicely shipped. Opened it up followed instructions as well as called customer servicer, had a few questions. I am currently using the performance Tune. It woke my Mustang up although I had many performance mods done prior to tune so the vehicle was already quick. The tune just polished up the performance, better throttle response and quicker acceleration. I would recommend this product for those who want a more exciting ride. Nice job AM.

    This tune makes your car shift vigorously and really throws you back in your seat! My wheels actually chirp like a manual car from the second shift.... When combined with a pypes dual exhaust and a BBK CAI, the power gain is easilly felt and it's shown on the streets... My 0-60 time went from a 7.2 stock to a 6.2 with all of these mods combined. 1 second difference! I definitely recommend it to anyone, but combined with the other mods listed really wakes up your v6. The only downside is that the power was too much for my traction at first and my wheels would soon out like crazy. Think about adding some weight to the back or adding a limited slip differential to get both those tires gripping! The exhaust helped my traction for some reason??? Have fun!

    Hang on to your seat-this thing rocks

    I was skeptical at first, being a V6 and having so many other Mods not perform to the hype. However I believe in AM and their products, so I took the plunge and I haven't looked back. This tuner rocks....after a quick install I hit the road slow at first then WOT and was amazed at how this car woke up from its factory slumber. All I can say is if you love the power and like to be pinned against the seat in all gears then this is for you.

    Completely Worth It!!!!!

    This product was the best thing I've done for this car, I didn't expected to make that much gain. But soon as I plugged it in a put it on the street Tune and took it out for a spin and WOW!!!! I chirped 4th gear! After all the mods I made to this car the tuner brought everything to life best investment so far.

    Unleash your Mustangs potential

    I have had my Bama X4 Tuner for 2 weeks now. My 2007 V6 4.0L is a powerhouse now. I keep it on performance mode. My Pony's tires chirp hitting 2nd gear, then jumps into 3rd. It feel like my Muscle car has balls now. I highly recommend this Tuner to make your Mustangs shift stronger and more torque. I have to now buy new tires now because of all the fun I'm been having with my Bama X4 Tuner.

    Worth the money!

    Just bought this tuner and it arrived in the mail, downloaded the updates and then plugged it in and it completely changed the car! Shift firmness is drastically increased, acceleration is much better. Switched my car back to stock a day later to see what it felt like and it felt like i was driving a prius! The live data feature is one of the best features in my opinion. I love the ability to view data while i drive. Overall a great product. I recomend this product to everyone with an auto mustang!

    Great results & Excellent Customer Service

    My wife bought the tuner for me for Christmas. Was fired up about seeing what it would do for my '06 Mustang. I installed a BBK CAI a couple of weeks prior to Christmas, and had already noticed a significant difference in performance. Christmas afternoon I could not wait to put a tune on her, but when I did the dreaded "Yellow Wrench" would come on. Returned to stock & it was gone. I called AM from the car immediately, and was told that when the info was turned in on my car that I had not listed the CAI ( Even though it says no tune required ). Within an hour three new tunes were emailed to me. Same problem though. Well with the weekend coming up I knew I would have to wait, Louis Max with AM was working on this for me though. He emailed me early Monday AM, and asked if I could check the Strategy Code, and email it to him. I did just that, and he emailed me back that the code was different than what they had. He said he would have new tunes for me to try soon. Less than a half an hour later the new tunes arrived. I got home from work, and immediately installed the Perfomance Tune. NO YELLOW LIGHT!!! WooHoo!!! It made a huge difference. Response is much better, you can feel the torque, and she runs through ( Automatic ) gears much snappier. I recommend the tuner to anyone wanting to give their V6 a kick in the butt. It's as though someone dropped a new engine in. Seriously! The customer service was second to none. They took care of me, and a special thanks to Mr. Louis Max. Great job! AM will get all of my business!! Next up will be Sceamin Coil, New plugs & wires!

    A World of Difference

    As much as I loved my stock V6, and as sexy as it looked, it was never exactly a powerhouse. Acceleration was disappointing, torque was weak and shifts would stall and constantly kick in a second AFTER I needed them (it is an automatic, unfortunately). After reading some of the reviews on here, I decided to cave and try out the tuner. First, let me say--I went right for the 93 octane race tune. With gas as cheap as it is now, I can fill up on no ethanol 93 for less than I'd pay for 87 a few months back, so I took the plunge and I'm so glad I did. The engine note is throatier and deeper even when just idling, and the first thing passengers mention when I take them on a joyride to show off the difference is how it 'sounds like a V8' (it doesn't quite, but the improvement from stock is still night and day). Throttle response went from lethargic to immediate, and every shift is immediate, smooth, and without hesitation--a complete 180 from stock. Acceleration left me screaming words in excitement that aren't allowed to be posted in this review, with 0-60 runs absolutely throwing me back in my seat like I thought this car never could! I've gone from feeling like I'm pulling teeth to get the acceleration I need to having to exercise extreme caution every time I hit the gas to not zoom way past the speed limit. Before I got used to it, I actually screeched the tires going 0-30 from a complete stop. All my buddies have given the change similarly glowing reviews and bug me to drive them all the time, always insisting I take the way with the highest speed limits. Honestly, it feels like a different car, in the best way possible. All my gripes about the V6 have been fixed, and I don't even mind so much it being automatic since the race tune has so far known exactly when to shift with perfect precision. You won't get better horsepower to dollar ratio than this, but the difference goes far beyond the '19+ hp' promised in the description, at least in an auto. Every single aspect of this car is transformed for the better, to the point where even just driving to the grocery store and back at the speed limit is a fun experience. Stop waffling and buy it. If you can't afford it, just skip dinner for a month or something. So worth it.
