Stage 1 remapping in Penarth
Only 40.3% of working residents in the Penarth built-up area drove to work in the 2021 Census, below the England and Wales figure of 45.1%, and just 10.4% travelled 10 km or more, a little over half the 19% across England and Wales. With Cardiff 6.4 km away, the commute here was often a short one, so a car's harder work tends to come elsewhere: the motorway trip, the holiday run or towing. Those are the jobs where a diesel with Stage 1 remapping feels different. Nothing physical changes: fuel, boost and timing are adjusted in the engine software, within its limits, and the result is more mid-range torque, so merging, overtaking and pulling a trailer all take less effort.
