Stage 1 remapping in Sunderland
Close to a third of privately kept cars in the Sunderland council area are diesel: 33.7% at the end of June 2026, the 14th highest share of the 104 largest towns we cover. That comes to 39,353 diesel cars in private hands. For those drivers, the case for Stage 1 remapping rests on mid-range torque: overtaking and joining faster roads take less effort, and the car needs fewer downshifts. It is software only, with the engine's limits respected. Fuel use may change slightly, depending on how you drive. If the car has a DPF, EGR or injector fault, that is repaired first.
