Back to Makes

Seat At Celtic Tuning, we provide a wide range of SEAT ECU remapping and chip tuning services for petrol and diesel models. Our software is developed in-house and fully tested on the dyno. This ensures precise upgrades that improve performance, drivability, and reliability.

Our SEAT ECU remaps offer sharper throttle response, more power, and smoother power delivery throughout the range. Diesel owners, especially those with models like the Leon, Ibiza, Alhambra, and Exeo, can benefit from better fuel economy. This makes our tuning perfect for those who want both performance and efficiency.

We support the entire SEAT lineup, from compact models like the Ibiza, Arosa, and Mii to family cars and estates such as the Leon, Toledo, Exeo, and Altea. Our coverage also includes SUVs like the Ateca, Arona, and Tarraco, as well as the versatile Alhambra. For enthusiasts, our tuning maximizes the potential of performance-focused models such as the Leon Cupra and Ibiza FR.

All our software is 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 industry standards.

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