How to improve the performance of my BMW M9 engine?

I recently purchased a BMW M9 and I'm not satisfied with its engine performance. It feels sluggish and lacks power. Are there any modifications or maintenance tips that can help improve its performance?

Firstly, make sure to regularly change your engine oil and filter. This can greatly improve the engine's performance and longevity. Additionally, consider upgrading your air filter to a high-performance one, as it can improve air flow to the engine. Lastly, look into tuning options or ECU remapping to optimize your engine's output.

I would also recommend checking your spark plugs and ignition system. Worn-out spark plugs can cause engine misfires and affect performance. If necessary, replace them and make sure the ignition system is functioning properly. Another thing to consider is upgrading the exhaust system for better flow and more power.
