How can I increase my Audi 80's horsepower and torque?

I recently purchased a used Audi 80 and I love everything about it except for its lack of power. I want to give it a boost, but I'm not sure where to start. I've heard of certain modifications that can increase horsepower and torque, but I'm not sure which ones are compatible with my specific model. Can anyone provide some guidance?

One of the best ways to increase horsepower and torque in your Audi 80 is by installing a performance chip. This will recalibrate your engine's settings and allow for a significant boost in power and torque. I've personally had great success with the APR ECU upgrade. It's a bit expensive, but definitely worth the investment.
