Couldnt find this after searching but where should i run the bov vacuum line... i have no lines directly on my IC piping right now. I have my wastegate routed into the plenum so when the tb shuts it instantly shuts the wastegate to get boost back up. I dont know where to hook the bov line to and if it matters. Should it be on the piping or the plenum.

There is a nipple on the back of the intake manifold past the throttle body that I have T'd off for my BOV and boost gauge. Works fine for me.

There one nipple on the back of the intake manifold, one under the throttle body and one on the side of the TB.

I used the side nipple for my bov and boost gauge.The nipple under the TB for the wastegate and the nipple on the back for the fuel pressure regulator.

Ok, I hooked my Blitz up like that, but it doesn't open, the compressor surges. Is there a way to adjust these? I didn't get a manual on it as it was used.
