For owners looking to go beyond a typical remap, NVM’s BMW B58 Stage 2+ package combines airflow, exhaust and fuelling upgrades with live dyno calibration to deliver up to 470bhp and 720Nm on 99RON fuel.
This package is suitable for the BMW M140i, BMW M240i, BMW 340i, BMW 440i, and BMW 540i running the B58 engine.
What Makes This a Stage 2+ Setup?
The key difference with Stage 2+ on the B58 platform is uprated fuelling alongside airflow and exhaust improvements.
This package includes:
- NVM shielded decat downpipe (F1 heat shielding to reduce heat soak)
- NVM PRORAM high-flow panel filter
- Genuine B58TU high-pressure fuel pump (supplied and fitted)
- Custom Stage 2+ dyno mapping session
By upgrading the high-pressure fuel pump, the engine can maintain stable fuelling at higher boost levels. This allows the calibration to safely extract more performance while keeping power delivery consistent under load.
What Can You Expect?
With supporting hardware and live dyno tuning, typical results are:
- Up to 470bhp
- Up to 720Nm
- Stronger mid-range torque
- Sharper turbo response
- More consistent top-end performance
The aim is usable performance you can feel throughout the rev range — not just peak dyno numbers.
Optional Gearbox Enhancement
XHP Custom Stage 3 gearbox mapping is available as an add-on. This improves shift speed, raises torque limits, enables rev-matched downshifts and enhances manual control — particularly useful at Stage 2+ torque levels.
If you’re researching BMW B58 Stage 2+ tuning, this package offers a balanced and properly supported route to 470bhp.
