About this job

The results

From 184hp as standard to 260hp, the BMW 320i gained 76hp, roughly 41% more power.

Torque rose from 290Nm to 420Nm (+130Nm), 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.

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
