At Celtic Tuning, we specialize in Rover ECU remapping and chip tuning for petrol and diesel engines. We write all of our software in-house and test it thoroughly on the dyno. This ensures that we offer upgrades tailored to improve performance, drivability, and reliability.

Our Rover ECU remaps provide quicker throttle response, more power, and smoother power delivery across the entire range. Diesel models often see better fuel economy, making our tuning a smart option for drivers who want both efficiency and performance.

We support popular Rover models, including the Rover 25 (1999-2005), Rover 45 (2000-2005), and Rover 75 (1999-2005). This ensures we cover the key vehicles from the brand’s later years. Each remap is designed to enhance the driving experience while keeping long-term reliability in mind.

All our software is fully developed and tested on our advanced 4WD Dynocom rolling roads. We have two 4WD Dynocom dynos at our head office in Newquay, Cornwall, and another at our Derby branch. This setup guarantees accuracy, consistency, and reliable results.

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