Stage 1 remapping in Dartford
Diesel is losing ground quickly in the Dartford council area. Over the year to June 2026, the number of privately kept diesel cars there dropped by 6.9%, from 11,132 to 10,369, while England's fell by 5.3%. Diesel is now just 18.7% of the area's private cars, well under the 29.1% for England. For the diesels that remain, Stage 1 remapping can make the engine feel stronger without changing any hardware. The work is done in software, adjusting fuel, boost and timing while keeping within the engine's limits. On a diesel, the clearest gain is mid-range torque, which helps when merging and overtaking. Changes in fuel use are modest and depend on how you drive.
