At Celtic Tuning, we offer specialized MG ECU remapping and chip tuning services for petrol and diesel models. Our software is developed in-house and fully tested on a dynamometer. This delivers custom upgrades that improve performance, drivability, and reliability.

Our MG ECU remaps deliver sharper throttle response, increased power, and smoother power delivery throughout the range. Diesel owners can also see better fuel economy, making our tuning perfect for drivers who want both performance and efficiency.

We support popular MG models from the early 2000s, including the MG ZR (2001-2005), MG ZS (2002-2005), and MG ZT (2001-2005). Each remap is crafted to enhance the driving experience while keeping the unique character of these models.

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 accuracy, consistency, and top results.

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