At Celtic Tuning, we offer a full range of Porsche ECU remapping and chip tuning services for petrol and diesel models. Each remap is written in-house and fully tested on a dynamometer. This ensures we deliver precise software upgrades that improve performance, drivability, and refinement while keeping the engineering quality of Porsche intact.

Our Porsche ECU remaps give you sharper throttle response, stronger torque, and smoother power delivery. For diesel models like the Cayenne and Macan, many drivers notice better fuel economy. This makes our tuning a great choice for those who want both performance and efficiency.

We support the entire Porsche lineup, from legendary sports cars such as the 911 (996, 997, 991, 992), the Boxster (986, 987, 981, 982), and the Cayman (987, 718), to high-performance SUVs like the Cayenne (955, 957, 958, 2018>) and Macan (95B). Our services also cover the Panamera (970, 971), so both luxury and performance vehicles benefit from our skills.

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 another at our Derby location, we ensure accuracy, consistency, and top industry standards.

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