How to increase the horsepower in my Audi A3?

I recently purchased an Audi A3 and I want to increase its horsepower. What are some ways to achieve this without sacrificing fuel efficiency?

One way to increase horsepower in your Audi A3 is by installing a performance chip. This will optimize your engine's fuel and air mixture, resulting in a boost in horsepower. However, keep in mind that this may also affect your fuel efficiency.

Another option is to upgrade your air intake system. This will allow for better airflow to your engine, resulting in a slight increase in horsepower. Additionally, make sure to regularly change your air filter to keep your engine running smoothly.
