Everything but Nav
Immediately went to the shop for Unitronic Stage 1+ ECU/TCU Tune, also "cold air", high flow intake for more volume, Autotech 3" cat back SS Exhaust. 270ish HP on the dyno. Hard to hook up on a wet road, so probably going to go in for a new differential to help with that soon.

Wheel and Tire
VW Budapest 18" wheels, with 235/40ZR-18 BFGoodrich g-Force COMP-2 A/S. These were the widest 18" all season hi-perf tires I could find. They ride and handle great!
