About this job

The results

From 340hp as standard to 420hp, the BMW M140i gained 80hp, roughly 24% more power.

Torque rose from 500Nm to 600Nm (+100Nm), 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

Thinking about the same for your BMW?

We come to you from our Weston-super-Mare base, across Bristol, Somerset, Gloucestershire, Wiltshire, South Wales and parts of Devon and Dorset. Results depend on the exact car, so we confirm what suits yours before quoting.
