BMW 330d N57 Stage 1 (December 2025)

This BMW 330d went from 258hp and 560Nm to 320hp and 660Nm with our Stage 1 calibration, a gain of 62hp and 100Nm.

Stronger mid-range pull

The calibration improves mid-range pull, throttle response and overall drivability, and is developed with reliability in mind for N57 diesel engines.

Add-ons

  • Speed limiter solution

Advanced dealer-level diagnostics were included before and after.

Is the N57 330d reliable after a remap?

A careful Stage 1 stays within safe margins. We tune 330ds across Bristol, North Somerset, Somerset and South Wales.

About this job

The results

Power went from 258hp to 320hp, an increase of 62hp or around 24%.

Torque rose from 560Nm to 660Nm (+100Nm), which is what you feel most in everyday driving: stronger pull from low revs and easier overtaking.

What the work involved

A Stage 1 remap is a software calibration for an otherwise standard car. We refine parameters such as boost, fuelling, ignition timing and torque limits within safe margins, so it pulls harder through the mid-range without any hardware changes.

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
