BMW 330e G20: Stage 1 Custom Dyno Tune, 413bhp

Most people buy a BMW 330e for company-car tax and economy. This owner wanted to see what the G20 plug-in hybrid could really do, so it came in for our Stage 1 custom dyno tune.

The numbers

The dyno measures the combined output of the 2.0 petrol engine and the electric motor. It arrived at 293bhp and 443Nm and left at 413bhp and 721Nm:

What 721Nm feels like

That is 278Nm more than it arrived with, peaking just after 2,600rpm. In practice the 330e pulls far harder through the mid-range, overtakes are over in a moment, and motorway pulls feel effortless, while it still drives quietly on electric power around town.

Hybrids are tuned properly

A hybrid is never a job for a generic file. Diagnostics and a health check come first, then baseline runs, then a calibration built around the car with live data logging and repeated runs, the hybrid system’s own strategies respected throughout. Original software backed up, fully reversible.
