Stage 1 remapping in High Wycombe
Within 4 km of High Wycombe are Hazlemere, at 3.6 km, and Flackwell Heath and Wooburn Green. The town lies along the Wye, with the Chiltern Hills all around it, and its road list takes in the M40 as well as the A40 and A404. On a diesel, Stage 1 remapping is a software change to the fuel, boost and timing settings, within the engine's limits, and nothing is fitted. The gain shows as torque in the mid-range, which is what you use joining a motorway such as the M40. Changes in economy, if any, depend on driving style and are small, and your insurer has to be told.
