At Celtic Tuning, we offer a full range of Renault ECU remapping and chip tuning services for both petrol and diesel engines. Our software is written in-house and fully tested on a dynamometer. This ensures precise calibrations that improve performance, drivability, and reliability.

Our Renault ECU remaps provide sharper throttle response, stronger torque, and smoother power delivery across the range. Diesel drivers, especially those with models like the Master, Trafic, Kangoo, Koleos, and Scenic, often experience better fuel economy. This makes our tuning a smart choice for both personal and commercial use.

We support the entire Renault lineup, from compact hatchbacks like the Clio and Megane to family models including the Scenic, Grand Scenic, Modus, Laguna, and Talisman. We also cover modern SUVs such as the Captur, Kadjar, Koleos, and Arkana. Our services extend to vans and light commercial vehicles like the Master, Trafic, and Kangoo, ensuring reliable performance across all sectors.

Our software is fully developed and tested on our advanced 4WD Dynocom rolling roads. With two 4WD Dynocom dynos at our head office in Newquay, Cornwall, and another at our Derby branch, we ensure precision, consistency, and top-quality standards.

For your peace of mind, Celtic Tuning also offers a mechanical breakdown warranty along with a 14-day money-back guarantee.
