Stage 1 remapping in Tonbridge
A roads make up Tonbridge's whole list of main roads: the A21, A26, A227, A228 and A2014. Without a motorway on that list, much local driving is at A-road speeds, where a diesel works in the middle of its rev range rather than cruising. That is the range Stage 1 remapping works on. The extra torque means fewer downshifts when a hill or a heavy load slows the car, and less need to rev it hard. The change is made in software, within the engine's limits, and nothing is bolted on. Your insurer has to be told about the remap, and any existing fault, such as an AdBlue or injector problem, is repaired first.
