ok, here's the deal: currently my vacuum routing is like this:

large nipple on top of intake goes directly to wastegate

small nipple on top of intake goes to fuel pressure regulator and blowoff valve

in my search/research, i have read to my understanding that the large nipple should be used for the bov only, the small nipple is to be run to the fpr, boost gauge and/or boost controller. also that the wastegate has its own dedicated source from a nipple on the intercooler piping.

so here are my questions:

1-is there anything wrong with my routing as listed above?2-i only have a nipple one ic pipe(the one going to the intake manifold)-can i use this nipple for the wastegate?3-if my routing is ok, can i tee off of the bov/fpr in order to hook up my boost gauge and manual boost controller?

thanks guys and gals

Why don't you just run it the way it should be instead of doing it the way you want? Its set that way for a reason. Just do your vacuum lines like your search says. That's correct, yours is not. Save yourself the hassle.

well i have absoulutely no problem running it how it is "supposed" to be. which is why i asked in the original post if the nipple on my cold pipe(intercooler pipe going to intake manifold) can be used for my wastegate signal- so can i use that?? thanks for the replies and help.
