About this job

The results

This BMW F32 440i B58 now makes 420hp, up from 326hp as standard: 94hp more, an increase of around 29%.

Torque rose from 450Nm to 600Nm (+150Nm), which is what you feel most in everyday driving: stronger pull from low revs and easier overtaking.

What the work involved

Stage 1 is calibrated for a car with standard hardware. By refining boost, fuelling, timing and torque requests within the engine's safe limits, it delivers stronger, smoother acceleration and sharper throttle response.

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
