I just recently purchased a 2012 GLI with 6spd DSG. Looking at possibly upgrading the performance, but have a couple of questions.

1. Anyone here upgrade with APR Stage 1 or 2 ECU? If so, how is performance and are you happy with it.

2. I also purchased the extended warranty at time of purchase. Car has warranty for 8 years or 100k miles. I am concerned it will void my warranty if I proceed? Can anyone confirm this?
