Stage 1 remapping in Northampton
Diesel still made up 42.4% of the cars and small vans given an MOT at test stations across NN postcodes in 2025, and the Volkswagen Golf was the most tested diesel car, with 6,211. In the West Northamptonshire council area, 33.3% of the 227,114 privately kept cars were diesel at the end of June 2026. That is a lot of diesel engines, and on a diesel the gain from Stage 1 remapping is mid-range torque: easier overtaking, joining the M1 with less effort, and steadier pulling with a trailer. It is a software change to fuel, boost and timing, kept within the engine's limits, with nothing bolted on.
