What Is Stage 2 on the BMW S55?

Stage 2 is where the S55 becomes what BMW should have delivered from the factory.

By removing the factory exhaust restriction and improving airflow and charge-air cooling, Stage 2 allows tuning software to safely run:

• Higher boost

• Cooler intake temps

• Faster turbo response

• Significantly more torque

Typical Stage 2 Gains

• +120–160 wheel horsepower

• +140–200 lb-ft torque

• Faster spool

• Stronger midrange

• Much harder top-end pull

This bundle supports pump gas, ethanol blends, and high-boost maps.

What’s Included in the BimmerTrend S55 Stage 2 Bundle

Every Stage 2 build requires a downpipe, so this bundle always includes one.

From there, you can add:

Everything in this bundle is designed to support high-boost S55 tuning without reliability issues.
