At Celtic Tuning, we offer a full range of Nissan ECU remapping and chip tuning services for petrol and diesel engines. Each remap is created in-house and fully tested on a dynamometer. This ensures precise upgrades that improve performance, drivability, and reliability.

Our Nissan ECU remaps provide sharper throttle response, stronger torque, and smoother power delivery. Many drivers of diesel models like the Navara, Pathfinder, Qashqai, X-Trail, and NV vans also notice better fuel economy, which reduces running costs while maintaining great performance.

We support the entire Nissan lineup. This includes compact cars like the Micra, Note, Primera, Pulsar, and Almera, as well as crossovers and SUVs like the Juke, Qashqai, Murano, Terrano, and X-Trail. Our services extend to light commercial vehicles such as the Interstar and Primastar, improving efficiency and usability. For performance fans, we also tune sports models like the 350Z, 370Z, and GT-R, allowing these legendary cars to reach their full potential.

All of our software is developed and tested on our advanced 4WD Dynocom rolling roads. We have two 4WD Dynocom dynos at our headquarters in Newquay, Cornwall, and another at our Derby location. This setup ensures accuracy, consistency, and trustworthy results.

To provide complete peace of mind, Celtic Tuning also includes a mechanical breakdown warranty and a 14-day money-back guarantee.
