Marine Remapping in Sussex

Marine Remapping & ECU Tuning Specialists​

At NXT Performance, we provide expert ECU remapping for marine vehicles, including boats, jet skis, and personal watercraft (PWC). Factory engine maps are often conservative to meet emissions and broad market standards, which means your marine engine isn’t performing at its full potential.

Our custom marine remaps are designed to unlock extra power, improve throttle response, enhance fuel efficiency, and deliver a smoother, more responsive ride. Whether you’re seeking more acceleration, better fuel economy for longer trips, or simply want to optimise your craft’s performance, our ECU tuning service provides a safe and reliable solution.

With years of experience in tuning high-performance engines, we ensure every remap is tailored to your specific boat or jet ski, giving you more control and more enjoyment on the water.
