Stage 1 remapping in Farnworth
Only 15.8% of working residents in the Farnworth built-up area travelled 10 km or more to work in the 2021 Census, below the 19% for England and Wales, and just 2.2% went 30 km or more. Kearsley is just 2 km away. Driving like this is mostly done at low and middle revs, and that is the range Stage 1 remapping works on. The remap is a software change to fuel, boost and timing settings, inside the engine's limits, and on a diesel the extra mid-range torque means cleaner pulling from junctions and fewer downshifts in slow traffic. Nothing is bolted on, so the car looks no different.
