Stage 1 remapping in Guildford
Diesel is thinning out faster in the Guildford council area than in England overall. Privately kept diesel cars there went from 18,381 to 16,803 over the year to June 2026, down 8.6%, while England's number fell 5.3%. Diesel is now 22.1% of private cars in the council area, against 29.1% for England, and 62.4% run on petrol. If yours is one of the diesels staying on the road, Stage 1 remapping is a way to get more out of it without changing car. What you feel is mid-range torque: acceleration is more responsive, the car asks for fewer downshifts, and a loaded boot or a trailer makes less difference to how it pulls.
