At Celtic Tuning, we offer a full range of Mitsubishi ECU remapping and chip tuning services for both petrol and diesel models. All our software is developed in-house and extensively tested on a dyno. This ensures precise upgrades that improve performance, drivability, and reliability.

Our Mitsubishi ECU remaps provide sharper throttle response, more power, and smoother power delivery. On diesel models like the L200, Outlander, and Shogun, many owners also experience better fuel economy. This helps lower running costs while keeping performance strong.

We support the entire Mitsubishi lineup, including everyday cars such as the Colt, Carisma, Galant, Grandis, and Space Star, as well as SUVs like the ASX, Outlander, Shogun, and Shogun Pinin. Our services also cover the practical L200 pickup and high-performance models like the Lancer and Lancer Evolution X, helping these iconic vehicles reach their full potential.

All our software is developed and tested on our 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 and consistency in our results.

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