Smart City (W450) 2000-2004 0.7 Turbo Brabus 74bhp remap figures

Who is the Stage 1 map for?

• Drivers who want a noticeably quicker car from a software-only change, with no new parts.
• Daily drivers who want stronger mid-range pull and a sharper throttle.
• Anyone who wants the biggest gain we list without fitting hardware.

What this means for your City

Turbocharged petrol engines respond well to calibration changes: boost and timing are the main levers, and the result is a flatter, stronger torque curve as well as a higher peak.

The ECU recorded for this variant is a Bosch MEG1.0/1.1. 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.
