- Drivers who accept that a bigger gain means more of the car has to be checked and prepared first.
What Stage 2 needs
Stage 2 is written around supporting hardware. For an engine like this one that is typically a freer-flowing intake, an upgraded intercooler and a less restrictive exhaust. We confirm the exact parts for your car before any work starts.
- A diagnostic check and a read of your ECU come first.
- We look at the condition of the parts that will carry the extra power before we quote.
- Stage 2 is intended for off-road or competition use.
What this means for your A Class
Diesel remaps work mainly on boost pressure, fuel delivery and torque limiters, which is why the Nm gain is usually the figure you feel in everyday driving, particularly when overtaking or towing.
This car is listed with a Bosch EDC16C31 engine control unit. Older engine management is simpler to work with, but age matters: worn sensors, leaks and tired components can hold back what a remap delivers, which is why we run a diagnostic check first.
We remap at our Belgrave Gate workshop in Leicester, or at your home or work within 30 miles, and every job starts with a diagnostic check.
Please note: these are expected figures, not guarantees. Real results vary with the condition of the vehicle, the ECU software version, fuel quality and the hardware fitted. Some options - including Stage 2 and anything that needs extra hardware - are for off-road or competition use only. We check every vehicle first and confirm what is achievable before any work starts.
