At Celtic Tuning, we offer a complete range of Citroën ECU remapping and chip tuning services for petrol and diesel models. Each remap is created in-house and fully tested on our dyno. This process allows us to deliver custom software that maximizes performance, improves drivability, and maintains great reliability.

Our Citroën ECU remaps provide sharper throttle response, more power, and smoother power delivery across the range. Many customers with diesel engines also enjoy better fuel economy. With years of experience, we offer tuning solutions for everything from compact cars to MPVs, SUVs, and vans.

We support popular models like the C1, C2, and Saxo, as well as the larger C3 and C4 series, including the Aircross, Picasso, Cactus, and the latest C4 X. Executive models such as the C5, C5 Aircross, C5 X, C6, and C8 are fully covered. We also cater to families with options like the Berlingo, Dispatch, Relay, SpaceTourer, Synergie, Xsara, and Xsara Picasso. Enthusiasts will find performance options like the DS3, DS4, and DS5.

All 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 and consistent, top-quality results.

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