About this job

The results

This BMW 440i now makes 475hp, up from 326hp as standard: 149hp more, an increase of around 46%.

Torque rose from 450Nm to 730Nm (+280Nm), 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 2 calibration, written for a car with supporting hardware such as intake, intercooler or exhaust upgrades. With the engine breathing more freely, the software can safely ask more of it than a Stage 1 map.

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
