    Increased HP and Torque. From the factory, the manufacturer programs their vehicles to cater to the needs of the daily driver, not the performance enthusiast. After loading a SCT pre-configured strategy tune on a vehicle, even a bone stock, unmodified Mustang will realize noticeable gains in Horsepower, Torque, and Fuel Economy.

    Increase your mod's potential. Factory computer settings are calibrated for the original factory components. When making performance modifications, you need to recalibrate the vehicle's computer to realize the full potential that these modifications can achieve.

    Compact Design. The SF4/X4 Power Flash Tuner measures in at 2.7” wide X 5.5” tall making it much smaller than the original SF3/X3 for easy storage in your center console or glove box. The cord is detachable and there is no battery or power supply needed. It uses the power from your vehicle's diagnostic port or computers USB connection.

    Full Color Display. The SF4/X4 Power Flash Tuner features a full color 2-3/4" diagonal LCD screen with user adjustable portrait or landscape modes. The SF4/X4 also has a convenient power saving auto dim feature.

    Built-in WiFi. The SF4/X4 Power Flash Tuner is now WiFi-capable meaning you will no longer have to plug it into your PC/Windows computer to receive the latest SCT firmware updates.

    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 a SCT pre-configured strategy 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.

        What is the difference/benefit of the SCT tuner vs. the BAMA tuner? They look exactly the same...?

        • The SCT SF4/X4 Power Flash Tuner does not come with custom tunes whereas the Bama tuner comes with custom tunes and free tunes for life.

        What's is the difference between the bama tuner x4 and the sct sf4? Do both have free tunes for life? I would like to know the difference before I purchase either one thanks

        • The tuners themselves are the same, but the BAMA x4 sf4 tuner is included with our free tunes for life program, whereas the SCT tuner of the same style does not come with free tunes for life.

        I recently purchased this the SCT SF4 tuner and during set up it "asks" if the car has a Steeda CAI. I am considering purchasing the Steeda CAI and I was wondering if tunes are already pre-installed on the tuner, or do I have to get custom tunes. Please let me know. Thanks!

        • With the SCT tuner, this will come with preloaded tunes that you can download onto your car for what mod you have. However, since you bought the tuners from us you will be automatically enrolled in Bama's free tunes for life if you wanted to get a custom tune as well! Sincerely,

        how many tunes can this device hold if any?

        • The SCT SF4/X4 Power Flash Tuner would be able to hold up to 10 tunes on the device.

        Helpful (7)

        Will this tuner get better use of any CAI kit? Assuming that it would program the computer to allow for more airflow in the intake.

        • Any aftermarket cold air intake will benefit and create more power with an new computer tune to the motor. Allowing the vehicle to pull more air will overall make additional power even if you cold air intake does not require a tune.

        I have a Roush M90 supercharger and was thinking about doing the VMP power pack for a little bit extra power, and it says that this tuner is required for that pack. Would the Bama version of this SF4/X4 tuner work as well, or is it only the SCT version? Because, I like how you get free tunes for life with the Bama version, but I don't think this one offers that. 0 answer

            Really made a difference

            First time ever doing a tune on any car let alone my Mustang so was skeptical. It really made a difference though. Was very easy to use. Plugged in and worked right away.

            Good buy

            I beleive my car had a tune in it when I purchased it but now I know exactly what tune is in it and i can easily load new tunes in the future. It was exactly what I wanted and was pretty easy to install even though I had some unknowns with my car.

            The tuner really helped to open up the car a bit it made it feel more responsive as well as helping balance out all of the extra coming in with the bigger throttle body and Intake system definitely worth the purchase

            Save your money

            Preloaded tunes don’t work at all and AM fails to mention anywhere that tuners are NON REFUNDABLE until you actually try to refund it so it’s a waste of $400 you’re better off just going somewhere and getting a tune

            Amazing!

            So I bought this and went with MPT 91 performance tune and it is night and day difference. The throttle response is so much better the trans turning shifts so much fast and cleaner, not to mention the overall power gains. If you are on the fence with this go ahead and buy it!

            03 cobra sct x4 tuner

            This tuner has worked great for what I needed, switching tunes back and forth from e85 and 93 also the datalogging is what I needed for my tuner to adjust things on the fly for me. Easy to use easy to understand and navigate. Have been leaving it plugged in because the gauge display comes in handy.

            2010 Mustang GT automatic must have.

            Hello folks, a 2010 GT as you know has a 3 valve 4.6 final year before the Coyote. It is not a bad motor but as I had previously owned a coyote, a bit doggy. Good year for the 4.6 however it needs something more. This tuner definitely woke up this horse. It felt like 20 HP but is probably more like 10-12 with second gear rubber with automatic and stock air box. Throttle is much more sensitive and it just constantly wants to go faster. Feels like a high strung motor. I plan to put in 373 gears and know from experience that Mickey Thompsons will be required. I think if you want a stock high speed cruiser with an automatic, leave it stock. But if you are like me, that just is not good enough. Buy the tuner.

            I’ve got an 07 4.0 fbo. I was looking for more power without swapping gears or engine. Decided to tune it, boy was that smart. Fr it opened up the engine a lot more. Idk how much more power it gave me but I noticed a quicker throttle response and a difference in the torque. I can definitely tell the difference in the power. Watch out 4.6s I’m coming for you.

            My guy has been talking of nothing but a tuner for his mustang for over two years. I finally got it for him for Christmas and he was sooooooo excited. He took his car out for the afternoon to check his 0-60 before and after tuning and he commented that it trimmed off half a second on the economy tune. Whatever that means. The one down side is that he wants to buy more expensive gas now, and I pay for gas!
