Right now I have my BOV hooked up to my brake booster line, and my WG coming directly out the back of my intake mani w/ nothing T'd (Other than the BOV to brake booster). Should I connect my WG to the little nipple on my intake piping (Right before TB), or is it supposed to be on the intake manifold?

I would make the wastegate's vacuum line dedicated to the brake booster line.
BOV can run from one of the smaller intake man. vacuum ports.

I have had better boost response and less tendency for the wg to crack open early by hooking up the wg to the brake booster source.

 

For some reason though when I connect the BOV to one of the other intake mani vacuum lines...it just doesn't do anything. All I hear is my WG/turbo spool down when I let off the gas...and now when I let off it's a swoosh of air coming from the BOV. I'll try switching just these two lines tomorrow though and see how it works.

when i had my greddy type-s hooked up to the fpr vacuum line with the wg and boost guage, it sounded like crap and there was a delay in the blow off.

i gave it it's own vacuum line off the brake booster and response and sound was 100 times better.

 

If your gonna tap the brake booster for a vaccum source, do you use a tee and line that are the same diameter as the booster line itself? Or do you use an adapter to neck down the the smaller vaccuum line? Nevermind, did a search.
