Stage 1 remapping in East Grinstead
East Grinstead's nearest neighbouring towns are a fair distance off. Horley is 11.6 km away in a straight line, Crawley 11.7 km and Oxted 13.2 km, with Crowborough and Haywards Heath further still. Trips to them are proper drives rather than quick hops, and a good share of the mileage is done at a steady pace on A roads. Stage 1 remapping is noticed on driving like that. It alters the engine's fuel, boost and timing settings in software, within the engine's limits, without adding any parts. On a diesel the gain is mid-range torque, which shows when you overtake on an open stretch or climb with passengers and luggage aboard.
