Renault Master 2003-2011 2.5 DCi 100bhp remap figures

Who is the Stage 2 map for?

• Owners who have fitted, or plan to fit, supporting parts such as a freer-flowing intake and exhaust.
• Enthusiast, track and competition cars: Stage 2 is intended for off-road or competition use.
• 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 Master

On a diesel the biggest change is normally torque: the remap changes how much fuel and boost the ECU allows across the rev range, so pulling power arrives earlier and holds on longer.

Engine management is by a Bosch EDC16+C36 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.
