    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.

    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.

        5 Top Rated Questions

        My truck already has performance parts and the roush tune configured for those parts. I want to add my parts to my truck which will throw off the current tune. Would I need a custom tune with access to a Dyno or would the pre loaded tunes work?. Should I take it back to Ford to have them retune it. It did not come from the factory with the tune it was the performance level 2 tune.

        Recently bought and installed the Borla ATAK Dual Exhaust System - Rear Exit for my 2015 F150 3,5L twin turbo ecoboost now having engine light and engine issues possibly ECM ??? will this programmer fix my issue? should i have welded this muffler together or is the clamps that came with it ok? not sure why im having performance issues or engine light

        • That exhaust system should not cause the problem you described, so tunes will not fix that issue. The issue is either a defective exhaust, improper installation of the exhaust, or something unrelated.

        Will this tuner allow me to disable the auto-start/stop feature? Also will it allow the speed limiter and what amount?

        • This tuner will not be able to offer the disabling of the auto-start/stop feature. A custom tune would be needed to adjust the speed limiter.

        Hello, I am wondering if this tuner will have to be continuously plugged in to the OBD port or can I detach it after I download the tune? THANKS!!!

        • Thank you for your question! The tuner will not need to remain plugged in after the tune is uploaded to the vehicle.

            Does what it says.

            Being in California, I’m limited to the 91 octane tune so I’m missing out on the power gained with 91 octane tune and that alone put some life into my 15 3.5L ecoboost f150. I’ve dealth with a handful of tuning systems over the years and although a slight pain to set up out the box, it’s one of the better handhelds out there. It’s canned tunes won’t make crazy power like a custom tune will but it still will put a grin on your face every drive.

            The big hype

            This product does do a speedometer delete. And it does what it says it willl do. But get ready to spend some money on a mechanical bov the ebov just keeps blowing off especially when going uphill. ISCT needs to redo program for ecoboost or I can look for other programs to download on there programmer. I mean we should be able to control when the ebov blows off.

            Great tuner.

            The connection of the TUNER and downloading a tune was quite simple. The difference in the performance of the truck was immediately noticeable. I may in the future load other tunes but right now I am pleased with the performance.

            Open the box, update the tuner, can take 10-15 to update on the computer. Plug it into your OBD II port and its that simple, def feel a change.
