Full Custom Tuning ($450)
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 4 weeks of the purchase date or upon reaching 4 revision files, whichever comes first.
