How to improve the performance of a BMW M5?

I recently purchased a BMW M5 and I'm disappointed with its performance. Is there anything I can do to improve its performance?

Firstly, you can start by upgrading the air intake and exhaust system to improve air flow. You can also consider a performance chip or ECU tune to boost horsepower and torque.

You can also invest in high-performance tires and suspension upgrades to enhance handling and grip. Don't forget to regularly maintain and tune your car to keep it in top shape.

Also, consider getting a re-geared differential for better low-end power and acceleration. And of course, don't underestimate the power of regular professional detailing and waxing to improve aerodynamics.
