Yeah, I'm Apfu there too.
Got turned on to them by some of the folks over at ls2gto.com. I've been doing most of the installs myself in the driveway, mostly bolt-ons. I've ordered mostly from Bob at Preceision Porting/Motorsports, he has been awesome to deal with. I've had tuning done by Ryan at RevXtreme but will probably have Jeremy Formato (independant tuner) tune it again in a month or so after the next round of mods.
