At Celtic Tuning, we offer a wide range of Jaguar ECU remapping and chip tuning services for both petrol and diesel engines. Every remap is developed in-house and fully tested on a dynamometer. This ensures we deliver upgrades that improve performance, drivability, and reliability. 

Our Jaguar ECU remaps provide sharper throttle response, increased power, and smoother power delivery across the entire model range. Diesel engine owners often see better fuel economy, making our remaps suitable for those who want both performance and efficiency.

We support Jaguar’s full lineup, from classic saloons like the X-Type and S-Type to executive models such as the XE, XF, and XF Sportbrake. We also cater to fans of sports cars with tuning options for the XK, XK8, and F-Type. SUV owners can take advantage of remaps for the E-Pace and F-Pace. 

All of 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 precision, reliability, and top-notch results.

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