BMW N55 3.0L Turbo
The BMW N55 3.0L single-turbo inline-six is one of BMW’s most iconic modern engines responsive, smooth, and highly tunable. With conservative factory calibration, there is significant headroom for safe, reliable gains. TuneZilla’s N55 stages deliver sharper throttle response, stronger mid-range torque, and a more exciting top-end while preserving the OEM refinement BMW owners expect.
Stage 1 Features
Increased boost pressure with safe factory fail-safes retained
Sharper throttle response with smooth, linear pedal progression
Stronger mid-range pull and improved high-RPM power
Perfect for completely stock vehicles—or those with a simple intake upgrade
Stage 1 is the ideal entry point for owners seeking a reliable, noticeable jump in performance without requiring mechanical changes.

Notes
Maintenance & Reliability Disclaimer
The N55 is a robust platform, but any increase in boost and torque places additional stress on the engine and driveline. To ensure long-term reliability, customers must maintain the vehicle properly.
Before tuning, we strongly recommend verifying:
Charge Pipes: The OEM plastic charge pipes are known to crack, even on stock vehicles. Ensure yours is not cracked or leaking and consider upgrading to an aluminum or reinforced aftermarket pipe.
Spark Plugs & Coils: Weak ignition components can cause misfires at higher boost levels.
Intercooler health: Ensures stable intake air temperatures under load.
Up-to-date oil and filter changes.
TuneZilla is not responsible for failures caused by pre-existing mechanical issues, worn components, or lack of maintenance.
