At Celtic Tuning, we provide a complete range of Cadillac ECU remapping and chip tuning services for both petrol and diesel models. Each remap is developed in-house and fully dyno-tested, allowing us to deliver maximum performance, improved drivability, and tailored solutions for your vehicle.

Our Cadillac ECU remaps unlock greater power and torque, sharper throttle response, and in many cases, better fuel economy. With years of development, we offer tuning solutions that transform the way your Cadillac drives.

We currently support models including the Cadillac BLS (2006 >) and Cadillac CTS (2008 >), with remaps available to enhance both performance and efficiency.

All of our software is fully dyno-developed and tested on our state-of-the-art 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 the highest quality standards.

For complete peace of mind, Celtic Tuning also provides a mechanical breakdown warranty alongside a 14-day money-back guarantee.
