Suzuki is known for making compact, reliable cars that offer great value, ranging from city-friendly hatchbacks to capable SUVs. At Celtic Tuning, we reveal their hidden potential through our ECU remapping and chip tuning services for both petrol and diesel engines. All software is developed in-house and fully tested on the dyno, ensuring every upgrade meets your expectations.

Our Suzuki ECU remaps improve throttle response, provide smoother power delivery, and increase pulling power throughout the rev range. Petrol models like the Swift, Ignis, and Splash feel more energetic and fun to drive, while diesel models such as the Grand Vitara, Vitara, and SX4 often see both enhanced performance and better fuel economy.

We support the entire Suzuki lineup, including the Grand Vitara (1998 onwards), Vitara (2015 onwards), SX4, and SX4 S-Cross, along with smaller cars like the Swift, Ignis, and Splash. Each remap is carefully designed to boost driving enjoyment while ensuring long-term reliability.

All calibrations are created and tested on our advanced 4WD Dynocom rolling roads at our facilities in Newquay, Cornwall, and Derby, giving you confidence in both accuracy and consistency.

For your peace of mind, all Celtic Tuning upgrades come with a mechanical breakdown warranty and our 14-day money-back guarantee.
