Stage 1 remapping in Havant
Motorway links are a big part of Havant's road list: the M27 and A3(M) are both on it, alongside the A27 and A3. Stage 1 remapping does not make a car faster at the top end so much as stronger in the middle, and on roads like these that shows when overtaking: moving out past a lorry, the car responds in the gear it is already in. It is a change to the engine's software settings, made within the engine's limits, with nothing bolted on. Around town the car drives just as before, only with a little more in reserve when you ask for it.
