Sinister Performance, LLC. Unsupported GM OBD-2 PCM tuning
Description:
Our tuning services may be available for your GM PCM even if your application is not on the supported tuning list. In some cases, this service is only available if special software is purchased by us so we can tune your specific application. However, even if your application is on our supported list, some changes to the PCM's programming you request may require a special software purchase by us in order to perform. You will be notified of such circumstances before you spend any money with us.
Pricing:
Prices for such applications will depend on the specific case and needs of the customer. We will make the price available to you once we have your information and know your tuning needs.
