About this job

The results

From 431hp as standard to 500hp, the BMW M4 gained 69hp, roughly 16% more power.

Torque rose from 550Nm to 680Nm (+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.

We also tuned the gearbox, raising its torque limits to match the engine and making shifts quicker and more decisive, particularly in Sport and manual modes.

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
