Stage 1 remapping in Sutton
Sutton has the lowest diesel share of the 104 largest towns we cover. At the end of June 2026, just 11.8% of the 81,150 privately kept cars in the Sutton council area ran on diesel, against 70.3% on petrol. That changes the usual Stage 1 remap conversation. Here, petrol cars are the majority, and on a petrol car the remap works on the same kind of fuel, boost and timing settings as it does on a diesel, in software and within the engine's limits. Sutton's diesel drivers, a small group, will notice the extra mid-range torque most when overtaking.

Sutton is within the ULEZ, which can charge cars and vans daily. A remap does not change a vehicle's emissions standard, so it cannot change whether the ULEZ charges it.
