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.

how to load a custom tune to your SCT device.
And then using the handheld to program your vehicle.
