Subaru has built a strong reputation for making reliable all-wheel drive vehicles that perform well in any condition. At Celtic Tuning, we take that capability further with our Subaru ECU remapping and chip tuning services. We develop all our software in-house and fully test it on a dynamometer, providing upgrades you can trust.

Our Subaru ECU remaps improve throttle response, increase mid-range torque, and provide smoother power delivery throughout the range. Petrol models like the Impreza see better performance and improved drivability, while diesel models such as the Forester, Legacy, and Outback often gain fuel efficiency along with extra pulling power.

We offer tuning for the most popular Subaru models, including the Forester, Impreza, Legacy, Outback, and XV, covering both modern SUVs and performance-focused cars.

Every remap is developed on our advanced 4WD Dynocom rolling roads. We have two facilities at our main office in Newquay, Cornwall, and another at our Derby branch. This ensures accuracy, consistency, and top-quality results.

For added peace of mind, all our tuning comes with a mechanical breakdown warranty and a 14-day money-back guarantee.
