I just got done putting mine on. I bought it for $1785 shipped with about 2k miles from a reputable guy.
I love it! Sounds great, install was good, goes fast, oh yeah and it sounds great (I have a V1).
Add about a grand onto the final price and you'll end up with what it will really cost you.
I didn't use the boost retard, T-rex (Yet) or any of the air intake tubing
I already had a twEECer, wideband, DataQ and 255lph fuel pump, the oil pan tap.
Also bought:
42lb injectors
90mm LMAF (shoulda went bigger, it's 0.1v from being pegged)
GM 3bar MAP sensor
AFM Powerpipe
Better elbow for AFM powerpipe
Colder plugs (Autolite 24s at 0.028)
Misc vacuum lines, 1in tubing
Better fitting to go between block and
vortech oil T
Oil change
Punches for oil pan
Need to buy:
Methanol kit
Spark box
Takes a good weekend to install. The a/c line is a beast. I used some teflon paste on the oil fittings and after having one small leak out of the T, I got that fixed and it is solid now.
You want a tune. It's cheap insurance and will get you awesome drivability and power. A real no-brainer.

I did it over the course of about 4 weekends in 2-3hour chunks and daily drove the car during the week except for the last week.
The kit itself was very easy to install. Lining up the AFM powerpipe was the biggest pain.
