    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.

    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.

    AnthonyF

    • 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 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!

    ToddG

    • 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,

    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. Also the CAI I have installed doesn't require a tune, I was just wondering if it would help get more power from it.

    AnthonyF

    • Tuning and re-calibrating the motor will allow you to get better use out of any cold air intake you can install on the vehicle. Even if your cold air intake does not require a tune to work, your vehicle will still pull more air which will make additional power.

      Bang for buck!

      Started with the pre-programmed street 93 octane tune. I felt I wanted better output and requested the 93 octane performance tune. Quick response from the American Muscle staff was impressive. This device does require a short learning curve, but the SCT website and the intuitive software makes installing and using the tuner easy. The increase in engine performance combined with the changes in automatic transmission shifting points really adds punch. It increases the driving fun experience. Acceleration gains are such that I find I have to careful to avoid possible speed limit violations. I'm getting my monies worth!

      Wakes the car up

      Purchased the tuner with Bama tunes, unfortunately the first one I received bricked my ECU. Dealer was able to reflash and Bama/American muscle overnighted me a new programmer free of charge. Loaded the 91 SCT preloaded tune and the car pulls harder. 2nd gear used to chirp but now spins. SCT preloaded tunes do work and add power. Despite the first tuner failing I'm glad I made the purchase. 4 stars only because it bricked my ECU the first time... But I have to say customer service at AM/ Bama and SCT is outstanding. SCT is paying for the dealer reflash, and AM overnighted the 2nd tuner free of charge... They'll take care of you. This car is alot more fun to drive now and I dropped 2/10ths off my 0-60. Doesn't sound like much but I feel like it'd be almost 1/2 second if I could manage the wheel spin. Car has more passing power than before in the lower rpms and pulls better all the way through. 09 gt 5spd manual with 3.31 gears.

      Horrible tuning experience.

      Ever since I have tuned my car, I randomly stall out and my RPM's are everywhere while idling. Now I've tried to get a new tune on my car to try and fix it, but the tuners firmware is out of date, try to update it but the tuner has locked me out completely from using it on both my car and PC. SCT now has to force an update to my tuner so I can set it back to stock and update the tune. Seriously, what a pain.

      Unreliable

      I had the device 1 week used it to tune a s550 uk spec with a Lund tune the tune needed amending as the GT350 TB was being tricky to get right and on the 3rd data log the device threw a coms error. It no longer responds. On emailing I was told this needed a Remote Desktop session but on calling SCT to sort it They said I have to pay to send it’s to SCT USA it took 20 mins on the phone to find out I’d have to send it to them at my cost they would need 3weeks ! To fix it due to capacity issues (lots of broken devices) at first I was told I couldn’t have a temporary device as I’m outside the US but upon pushing they said if I wanted a temporary device they needed a £350 holding fee ??? Realy regret using them and wish I had gone for another tuning interface I now will be without the device for a month with shipping time added and I need to upload an amendment to my tune. Don’t buy this item !

      Since my car has only minor upgrades with the intake the headers and the exhaust the SCT tune was the perfect purchase for this because I could go in and manually select the options I wanted to change in my tune it was very easy and the performance is beyond noticeable love this purchase!

      So easy to use, plug it in and select your upgrades and how you want your vehicle to perform. The Tuner takes care of the rest and with the Maps for Life feature any changes you make in the future it's as simple of requesting a new map. Great product.

      This provides basic tunes that you can upload for a little more power for basic mods. If you’re going all out I’d recommend a Bama or even a dyno tune to keep em running strong.

      If you own a 96-98 Cobra with any form of Bolt Ons then do NOT purchase. Myself and numerous others w/ SN 95 Cobras who bought this overpriced plastic are regretting it. Any performance tune done other than the 3 pre-loaded (which idle to high) are causing major detonation/timing problems. When I contacted AM.com about this they wanted to correct my tune. I let them. Loaded the new tunes and all caused my car to massively detonate at or around 3k RPM, with every tune. They cannot get their stuff dialed in despite me the and others telling them of these detonation issues. A complete crapshoot if you spend $400 on this.
