1.2 ABOUT YOUR SCT DEVICE

AVAILABLE GASOLINE TUNES: 93, 91, and 87 octane.
AVAILABLE DIESEL TUNES: Performance, Street, Towing.
Note: Not all options are available for all vehicles.
• X4 VIN locks (marries) to a single vehicle. You cannot use the device to tune a new or different
vehicle, until you have returned the original vehicle back to stock, which will unlock the
device. You can only change vehicles 5 times before the unit is permanently locked. You can
do unlocks remotely right on the X4. Service charges do apply.
• Standard pre-programmed tuning files are designed for vehicles with minor performance
modifications such as; cold air kits, high-flow exhaust systems, and other basic modifications.
Vehicles that have aftermarket superchargers or turbochargers will require custom tuning,
which can be purchased only through authorized SCT Custom Tuning Dealers. To locate a
dealer near you, use the dealer locator on the SCT website at www.sctflash.com.
• If you later add a blower, turbo or nitrous to your vehicle or add a more 'wild' naturally
aspirated combination of parts, you will need to obtain a custom tune from an SCT dealer. The
X4 programmer is flexible enough so that your original investment will not be lost – it can be
loaded with a custom tune from the SCT dealer.
