Product Details

Full Custom Tuning ($450) (Available for Select Models Only)

For certain supported models, Sutphin Tuning offers Full Custom Tuning—a fully personalized approach built from a base file tailored to your specific vehicle and modifications. This option is designed for high-performance builds (typically 900HP / 800TQ and above) or for track-focused setups such as drag racing, road course or time attack applications where precision and control are critical.

Due to the level of expertise and time involved, all Full Custom Tuning sessions must be completed within 3 weeks of the purchase date or upon reaching 6 revision files, whichever comes first.


To check availability and receive a quote, please reach out to a Sutphin Tuning representative.

Advanced Tuning

Advanced Tuning goes beyond our fixed-cost OTS-style Complete tunes and allows for deeper customization within the factory TCU parameters. This includes adjustments for customers that upgrade turbos, upgrade the transmission or want to adjust a certain mode.
Note: Advanced Tuning is an additional charge beyond the base OTS tune.
To discuss your goals and receive a quote, please contact a Sutphin Tuning representative.
