Springfield Motorsport is where I got my blower installed. At the time, I was pissed about a few things...but looking back in retrospect, they really did a good job. Even fabricated a mount for my aftercooler coolant resevoir because it wouldn't fit with my Steeda strut tower brace. They are slightly pricey, but you get what you paid for I believe. They turn out a good number of cars all the time with limited manpower.
ALSO, Wheat (their tuner's name....seriously, his name is Wheat) is the man ****zle tuner. This dude hooked up my ride and kept the boost around 8-9 psi and mpg is like 21-22. Work was done about two months ago or so, I "occasionally" drive it like I stole it, and has been running strong the whole time.
Even went to a car show with the owner (who sponsored breakfast and the meeting spot for the ride to the show).
One other thing: look into the NCRMC if you haven't done so already.
