LOL.
UPDATE:
I installed my TIAL BOV, or more accurately, I had my TIAL BOV installed
After reading a bunch of threads on where to mount it I decided to place it as close to the throttle plates as possible. The main reason I chose this location over mounting it near the turbo is because I don't like the idea of the air flowing through the intercooler pipes reversing direction to bleed out the BOV. Unfortunately, because the stock elbow is made out of plastic there is a lot of distance between the first metal mounting point and the throttle body.
A friend of mine that works at a local Porsche tuner did the work. First we placed the flange on the pipe and traced an outline of the flange with a magic marker. Next my friend drilled a large hole and trimmed the edges of the hole to match the flange outline.

Notice the nice even welding bead. He used a wire brush to try to match the standard Greddy finish, but it's still a little off. I think I will end up polishing the pipes when the turbo install is complete.
Even though I still have the stock BOV installed I decided to connect the TIAL to verify that it is working. It sounds much different than the HKS bovs I have heard; it sounds kind of like a large stock BOV vented to atmosphere. It seems to open about 1 second slower than the stock valve, but I think it will speed up slightly when I remove the stock valve. As mentioned above I am using the 7lb rotary friendly spring. If anybody gets a BOV with a different spring Tial will switch it out at no charge.
I'm very happy to be completely done with one aspect of the turbo project.
