I just bought a 2012 a4 premium plus s line with 9,004 miles. I was wondering if i want to make this car faster what would be the first couple steps?? I don't want to put the engine at any risk but would like to add around 50 hp. Who out there has started to play with the 2.0t and has had success??

 

APR Tuning is known for their reliability (APR - High Performance Development for Audi, VW and Porsche Vehicles.)

A simple tune and upgraded diverter valve is exactly what you're looking for.
