Actually, to be accurate, I'm originally from Canada where I owned a series of turbo and NA legacy's.  Now that I'm in New Zealand, I've gone to a MY2002 B4-RSK.  The TT has never been available in Canada (one of the turbos would sit where the brake booster should be on the driver's side), so I was looking forward to getting one here.
So far, I've done an MRT 3" turbo-back exhaust and an Ecutek tune.  The tune needs to be tweaked a bit (scheduled), but I'm certainly impressed with what those Ecutek programmers have made possible).
Have also added a rear sway bar (formerly on my BE in Canada) and have a few other suspension upgrades in the pipe.
Am waiting on the last of the parts for a 4-pot front, 2-pot rear brake upgrade, with slotted rotors.  As you'll read in another post, I'm feeling a little uneasy about how the rear upgrade will go, as I've not heard from anyone who has actually done this on a BE.
