Maximize the efficiency and power of your International truck with a performance tune designed specifically for OBD-II equipped commercial vehicles. Whether you're operating a 4300, 4400, DuraStar, WorkStar, ProStar, or LoneStar (1996+ models), our performance chips deliver measurable improvements in throttle response, fuel economy, and overall drivability. Each tune is carefully calibrated to enhance your International's performance while maintaining the reliability and longevity essential for commercial operations, construction work, and long-haul driving.

Our performance tunes for International trucks address common concerns among owner-operators and fleet managers: throttle lag during acceleration, optimizing fuel consumption over long distances, and improving power delivery when fully loaded or towing.
