How to optimize engine performance in a BWM?

I have a BWM and I feel like there's more potential in terms of engine performance. What can I do to optimize it?

First of all, make sure your BWM is properly maintained. This includes regular oil changes, spark plug replacements, and air filter cleanings. Keeping your engine in good condition can significantly improve its performance.

Consider upgrading your BWM's exhaust system for better air flow and increased horsepower. This can be a bit expensive but it's worth the investment for a noticeable boost in performance.
