How do I increase the maximum speed of my Audi A4?

I want to push my Audi A4 to its limits and increase its top speed. What methods or modifications can I make to achieve this?

To increase the top speed of your Audi A4, there are a few things you can try. First, make sure your engine is in top condition by regularly tuning and maintaining it. Secondly, consider upgrading your turbocharger or installing a bigger one. Lastly, make sure your car's aerodynamics are optimized by adding a spoiler or diffuser.

One important factor that affects your car's top speed is the gearing ratio. You can try changing your car's gear ratio to get more power at higher speeds. However, be careful as this can negatively impact your car's acceleration.
