Today I splurged for the APR upgrade to the control chip. It's a minimal increase in horsepower and torque, as shown by the graph above, but what the heck, right? You never have enough (or too much) horsepower. The work was done by PURE Motorsport.
While I was there, I also ordered some wheel spacers and a slightly more aggressive exhaust system. There's probably not a lot more I can do to this S5 while I'm waiting for the Audi RS5 to come to the USA sometime later this year...
