Custom ECU tuning is a game-changer for the S58, allowing you to safely increase power and refine engine performance while maintaining reliability.

Managing heat is key to maintaining engine performance, especially under extreme driving conditions. Upgrading the cooling system helps prevent heat soak and maintains consistent power output.
Best Practices for Maintaining a Tuned S58 Engine

- Monitor Air-Fuel Ratios – Running a wideband oxygen sensor and proper tuning ensures optimal fueling and prevents detonation.
- Upgrade Fuel System – Consider high-flow injectors and fuel pumps to support increased boost levels.
- Regularly Inspect the Rod Bearings – Prevent catastrophic engine failure by keeping an eye on wear-prone components.
- Invest in Proper Tuning – A professional tune tailored to your setup ensures reliability and maximizes power gains safely.
