At Celtic Tuning, we offer specialized MAN ECU remapping and chip tuning services just for diesel engines. Our expert team creates software in-house to provide better torque, more pulling power, and improved efficiency for tough commercial tasks.

Our MAN truck remaps enhance engine performance for heavy-duty applications. This helps vehicles manage loads more effectively and deliver power more smoothly. Many fleet operators notice a drop in fuel use, which cuts costs for both long-haul and regional transport.

We support a variety of MAN models, including the TGA, TGL, TGM, TGS, and TGX. This ensures we cover the brand’s most popular trucks. Whether you have one vehicle or an entire fleet, our remaps are designed to deliver reliable gains in performance and efficiency.

All our software meets high standards to ensure reliability and consistency that operators can count on every day.

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