Note:
Not all options are available for all vehicles.
iTSX 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. To reset the Changes or Unlock device you will need to contact
SCT. 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.
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 iTSX 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.
