Currently I have omitted the vacuum lines needed for emissions per the Taboo Speed Shop diagram. I am running a Greddy 18G, Greddy Type S BOV, Tial external wastegate, and no boost controller. I came off the intake manifold and T'd to the BOV (large nipple, top one) and the side nipple of the wastegate. This is what the diagram showed except for the addition of a MBC which I am not using. Is this setup correct? The only other line I have is the one on the opposite side of the intake manifold T'ing to me boost gauge and FPS.

Especially since you are using a GReddy Type-S, you should not tee from your BOV (going to your intake manifold). The line from the intake manifold to the Type-S BOV should be exclusive (a direct line, no tee). The Type-S BOV is known for shuddering, which is made worse by not using a direct line to the intake manifold. Use this as a guide.
RRE I/C Pipe Installation Instructions
You should connect your wastegate to a pressure source from your turbocharger (if it has a nipple on its housing), or from your lower intercooler piping (you may need to place a nipple there yourself), but not from the BOV's and intake manifold's line.

Your other connection, for your boost gauge, sounds good. Basically, you splice the line coming out of your fuel pressure solenoid (FPS) prior to it going to your fuel pressure regulator (FPR), placing your tee there, and running a line to the boost gauge.
 
Unfortunately no luck with a nipple being on the housing. I guess I'll be adding one myself to my lower IC pipe. Thank you.
