BMW E89 Z4 2.5i Stage 1

This BMW E89 Z4 2.5i went from 192hp and 245Nm to 207hp and 265Nm with our Stage 1 calibration.

A sportier, more responsive roadster

Another naturally aspirated car, so the aim was a sharper and more responsive feel rather than headline numbers. The Z4 now responds more eagerly and pulls more cleanly to the redline.

Add-ons

  • Speed limiter solution

Can you tune a Z4?

About this job

The results

This BMW E89 Z4 2.5i now makes 207hp, up from 192hp as standard: 15hp more, an increase of around 8%.

Torque rose from 245Nm to 265Nm (+20Nm), 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
