When you purchase custom tunes or claim them with a tuner, you fill out a custom tune form that allows you to not only give us all the required information on your vehicle, but to select what tune setup you would like for your tunes. Depending on your vehicle, you can choose your octane (excludes diesel), engine preference, and transmission preference (Automatics only). The only exception to the engine preference is our ghost cam lope tune, which comes with our performance engine preference.
Then, once they are generated for your vehicle, they will be emailed to you. You simply download them to your Windows-based computer and use the SCT Device Updater to put them onto your programmer.
