THE JTUNEDIT APPROACH
MADE FOR RACERS. BY RACERS.
Performance-driven. Hands-on. Focused on the complete build.
GAS. DIESEL. ONE PERFORMANCE MINDSET.
JTunedit is built around real-world racing, hands-on experience, and a passion for extracting the most from performance vehicles. We develop custom engine and transmission calibrations around the vehicle in front of us—not a one-size-fits-all promise.
Our work spans GM LS/LT performance and modern diesel powertrains, including supported Duramax, Power Stroke, and Cummins applications. From street and track calibration to performance development and remote tuning, understanding your combination comes first.
Based in Columbus, Mississippi, JTunedit also offers additional service availability associated with Lake City, South Carolina. Remote tuning connects us with supported applications nationwide.
