At Celtic Tuning, we offer a wide range of DS ECU remapping and chip tuning services for petrol and diesel engines. We write all our software in-house and test it thoroughly on the dyno. This allows us to provide customized upgrades that improve performance, drivability, and reliability.

Our DS ECU remaps offer sharper throttle response, more power, and smoother power delivery across the entire model lineup. Many diesel drivers also notice better fuel efficiency, making our tuning a great option for both performance and economy.

We support the whole DS range, from compact models like the DS 3 and DS 4 to larger ones such as the DS 5, DS 7 Crossback, and DS 9. We also remap crossover and SUV models, including the DS 3 Crossback and DS 4 Crossback, ensuring we cover the brand’s most popular vehicles.

All our software is fully developed and tested on our modern 4WD Dynocom rolling roads. With two 4WD Dynocom dynos at our head office in Newquay, Cornwall, and an additional 4WD Dynocom facility at our Derby branch, we ensure accuracy, consistency, and top industry standards.

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