I just leased a new A4 2.0T Quattro, full S-line exterior and interior package, sport suspension, the works. I am looking to get a little more juice out of it however. I see that the APR chip with the EMCS upgrade gets you a bunch more power, and has the ability to switch between modes as well. Does this mod void the factory warranty? If not, is it reversible so that I can turn the car back in in stock form when the time comes? Thanks.

 

Nevermind, found the info I need
