Stage 1 remapping in Reading
Behind the Volkswagen Golf, the Land Rover Discovery was the second most tested diesel car in 2025 MOT tests across RG postcodes, with 4,758 vehicles. If a Discovery or something like it is your tow car, Stage 1 remapping is mostly about what happens in the middle of the rev range: a stronger pull when moving off with weight behind, and fewer downshifts on a climb. The settings changed are fuel, boost and timing, all in software and inside the engine's limits, and your insurer has to be told. The RG count covers the whole postcode area, with the BMW 3 Series and Mercedes-Benz E Class next in line.
