How can I improve the horsepower of my Audi A7 engine?

My Audi A7 doesn't have as much power as I'd like. What can I do to increase the horsepower without sacrificing fuel efficiency?

One option could be to upgrade the engine's air intake system to allow for a better flow of air into the engine. This can often improve horsepower and improve gas mileage at the same time. You could also consider installing a performance chip or tuning the engine to optimize its power output.
