At Celtic Tuning, we offer a full range of Jeep ECU remapping and chip tuning services for both petrol and diesel models. Our software is developed in-house and thoroughly tested on the dyno. This guarantees custom solutions that improve performance, drivability, and long-term reliability.

Our Jeep ECU remaps give you a sharper throttle response, more power, and smoother power delivery across the entire range. Diesel models often see better fuel economy, making our remaps a smart choice for those looking for both performance and efficiency.

We support the entire Jeep lineup, from rugged off-roaders like the Wrangler (JK) and Cherokee (KJ, KL, 2008–2010) to larger SUVs like the Grand Cherokee (WJ, WK, WK2) and Commander (XK). We also support modern crossovers such as the Compass, Renegade, and Patriot, ensuring wide coverage across the Jeep brand.

All our software is developed and tested on our advanced 4WD Dynocom rolling roads. We have two 4WD Dynocom dynos at our head office in Newquay, Cornwall, and another at our Derby branch. This setup guarantees precision, consistency, and top results.

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