At Celtic Tuning, we offer a full range of Land Rover ECU remapping and chip tuning services for both petrol and diesel engines. Our software is developed in-house and fully dyno-tested. This process gives you performance upgrades that improve drivability, power, and long-term reliability.

Our Land Rover ECU remaps give you sharper throttle response, stronger torque, and smoother power delivery throughout the entire range. Diesel models often see improved fuel efficiency, making our remaps a smart choice for those wanting both performance and savings.

We support Land Rover’s entire line-up, from the iconic Defender (1998 onwards) to the Discovery series (II, III, IV, V, and Discovery Sport). Our services also cover the whole Range Rover family, including the P38A, L322, L405, Evoque, and Range Rover Sport, as well as the versatile Freelander and Freelander II. Whether your focus is off-road ability, towing strength, or smooth road performance, our software is designed to deliver.

All of 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 accuracy, consistency, and results that satisfy Land Rover owners.

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