Stage 1 remapping in Newport
Nearly half the cars and small vans given an MOT across NP postcodes in 2025 were diesel: 45.9%. That covers the whole postcode area rather than Newport alone, but the council figures point the same way, with 33.1% of the 77,340 privately kept cars in the Newport council area running on diesel at the end of June 2026. For all those diesel owners, a Stage 1 remap is about the mid-range. The result you feel is torque at everyday revs, the kind that helps with a full boot, a trailer or a long climb, all from a change to the engine's software rather than its hardware.
