Stage 1 remapping in Bristol
Only 32% of working residents in the Bristol built-up area drove to work in the 2021 Census, far below the England and Wales figure of 45.1%. Diesel is thinning out too. In the Bristol council area, privately kept diesel cars fell 7.1% in the year to June 2026, one of the steepest falls of the 104 largest towns we cover, and diesel is now 19.4% of private cars. For the diesels that stay, Stage 1 remapping is a software job only: the fuel, boost and timing settings are changed within the engine's limits and nothing is bolted on. Most of the gain sits in the mid-range, which suits pulling away with a load or joining the M32.

Driving in and around Bristol
Bristol's Clean Air Zone, a Class D charging zone, covers a small area of central Bristol and applies to cars and vans. A remap does not alter a vehicle's emissions standard, so it does not change whether the zone charges it. Vans are common: the council area had 88 privately kept vans per 1,000 private cars at the end of June 2026, the 8th highest ratio of the 104, and 94.2% of its 15,784 vans were diesel. In 2025 MOT tests across BS postcodes, the Ford Transit and Volkswagen Transporter were the most tested diesel vans. The nearest service area, Gordano on the M5, is 8.7 km away. For a working van, the torque gain helps most when loaded, within what the clutch can handle.
