About this job

The results

From 190hp as standard to 220hp, the BMW X3 20d gained 30hp, roughly 16% more power.

Torque rose from 400Nm to 480Nm (+80Nm), which is what you feel most in everyday driving: stronger pull from low revs and easier overtaking.

What the work involved

This was a Stage 1 calibration: no hardware changes, just carefully refined engine software. Boost, fuelling, timing and torque limits are adjusted within safe margins for more usable performance every day.

The gearbox was tuned as well. A gearbox calibration raises the transmission's torque limits to suit the engine and can sharpen shifts and response, so both work together as one package.

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
