Stage 1 remapping in Redhill
With the M25 and M23 both among its main roads, along with the A23 and A25, Redhill has two motorways close at hand. Those are the roads where weight is felt most: a van with a full load or a car towing a trailer has to work hard to reach and hold motorway speed. Stage 1 remapping on a diesel adds torque in the middle of the rev range, which is exactly where that work is done. The remap stays within the engine's limits and nothing is added or bolted on. If the vehicle has a fault, such as a DPF or AdBlue warning, that is repaired before any remap.
