The SCT X4 Tuner has been redesigned from the ground up with a full color screen that is much larger than the X3/SF3 tuners that it will be replacing.

The overall size is now smaller and more compact. It measures in at 5" x 3" where as the older SF3 measured 7" x 4". The SCT X4 Flash Programmer still comes with performance improving "Pre-Loaded" tunes and will also hold a total of 10 custom and mail-order tunes.

SCT is revolutionizing the Mustang tuning industry with their new Power Flash X4 Tuner! SCT listened to all of the customer feedback and they delivered. The SCT X4 features a much larger screen than the previous SF3/X3 tuner. The screen is now color as well!

Gone is long bulky cable that made the SF3/X3 hard to store. The cable is now removable on the SCT X4. It also features built in WiFi. That means you don't have to have a PC to get the latest updates!!

The standard in tuning just got better. The SCT X3 or SF3 has been the staple in the Mustang tuning community for many years now.

However, the main complaints about it were it's physical size, the fact that the cord did not disconnect from the device, and it had a small, non color screen.

All of these have been addressed with the new SCT X4. It is significantly smaller in size. The cord does unplug from the device, meaning it fits great in your glove box or your center console. Plus it has a full size, full color screen.

SCT even added in a nice little Wi-Fi feature, allowing you to connect the X4 to your wireless network and download updates without ever having to connect the device to your PC or laptop.

Of course, the X4 comes with all of SCT's preloaded strategy tunes for '96 to present Ford gas vehicles, which includes our beloved Mustang and the '99 to '04 SVT Lightning.

It retains all of the X3's features, like DTC clear and check, vehicle info, device info, device set up, and my favorite, the on screen data logging. It'll hold up to 10 custom tunes. And can even be mounted to your windshield using SCT's optional windshield mount.
