Stage 1 remapping in Horley
Two neighbouring towns are almost the same distance from Horley: Redhill at 6.3 km and Crawley at 6.6 km, in a straight line. Reigate is 7.7 km away, and East Grinstead and Dorking a little further at 11.6 km and 13.2 km. Gatwick Airport is close by as well. With that spread of destinations, the same car might do a short hop to Redhill one day and a longer run to Dorking the next, and Stage 1 remapping is felt on both, because the extra mid-range torque on a diesel works at everyday speeds rather than only near the top of the rev range. The change is to the engine's settings, not its hardware.
