Mercedes-Benz Trucks Actros 2003-2005 580 578bhp Stage 1 Eco remap figures

Who is the Stage 1 Eco map for?

• Drivers who want the pull of a remap for overtaking, motorways and towing, with the engine tuned with economy in mind.
• High-mileage drivers who want better performance and a more efficient everyday car in one map.
• Anyone who would otherwise take full Stage 1 but cares what each tank costs.

How Stage 1 Eco compares with Stage 1

Full Stage 1 on this Mercedes-Benz Trucks Actros is expected to give 670bhp and 3110Nm (+92bhp, +411Nm). The Stage 1 Eco keeps about 75% of that power gain and 92% of the torque gain, so you get 647bhp and 3077Nm: 23bhp less and 33Nm less than Stage 1, with the map shaped for efficient, relaxed driving, so it suits you if you want the pull and care about running costs. Both sit above the standard 578bhp and 2699Nm.

What this means for your Actros

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.

The ECU recorded for this variant is a Temic. 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.
