About this job

The results

From 184hp as standard to 200hp, the BMW 520d gained 16hp, roughly 9% more power.

Torque rose from 380Nm to 420Nm (+40Nm), which is what you feel most in everyday driving: stronger pull from low revs and easier overtaking.

What the work involved

This was an economy-focused calibration, written for smoother low-down torque so the engine works less hard in everyday driving, while still feeling stronger than standard.

How we carried it out

  • Diagnostic scan for stored faults before any work
  • Stabilised power supply connected while programming
  • Original software read and saved, so the car can be returned to standard
  • Calibration written, then the car checked again afterwards
