At Celtic Tuning, we provide a complete range of Infiniti ECU remapping and chip tuning services for both petrol and diesel engines. Every remap is developed in-house and fully dyno-tested, enabling us to deliver tailored software that maximises performance, enhances drivability, and maintains excellent reliability.

Our Infiniti ECU remaps deliver sharper throttle response, increased power, and smoother power delivery across the model range. On diesel engines, many customers also benefit from improved fuel efficiency, making our tuning an excellent solution for both performance and economy.

We support a wide selection of Infiniti models, including the EX (J50), FX (S51) and G (V36), as well as newer vehicles such as the Q30, Q50 and Q70 (Y51). With years of development, our remaps transform Infiniti models into more responsive and rewarding cars to drive.

All of our software is fully dyno-developed and tested on our state-of-the-art 4WD Dynocom rolling roads. With two 4WD Dynocom dynos at our head office in Newquay, Cornwall, and an additional 4WD Dynocom facility at our Derby branch, we guarantee precision, reliability, and industry-leading results.

For complete reassurance, Celtic Tuning also provides a mechanical breakdown warranty alongside a 14-day money-back guarantee.
