This Stage 1 calibration enhances turbo boost response and optimises injection timing maps to deliver stronger mid-range torque and reduced turbo lag. Rail-pressure control is fine-tuned for cleaner combustion and lower smoke output, while adaptive EGR and DPF regeneration settings ensure reliable filter cleaning without drivability loss. Gearshift adaptations on the 6-speed manual gearbox provide crisper, more confident shifts under load. Designed to unlock the Navara’s hidden performance within OEM safety margins, this remap balances improved fuel efficiency with a noticeably more engaging driving experience.
