Angry vacuum lines

just wanna make sure i'm not missing anything here...

#1) the blow off valve uses one of the manifiold ports

#2) the port on the compressor side of the turbo is just a test port and is not used

#3) the best way to run the MBC (manual boost controller) is to get a source before the tb (my tb has an npt port before the plate, which i plan to use), this line then goes to the bottom port on the MBC, the side port on the MBC then connects to the side port of the WG, and the top of the WG gets vented to atmosphere

am i right???

Here is a picture i got from turbonetics web site. i am now running my valve for my ebc in place of the regulator(mbc), and my vacum line for the bov is coming off on my intake (behind the throttle body).

Your picture is not showing up. I think you have your mbc hooked up wrong. I tried it like that, and boost looked like it was going to keep climbing. The top of the wg should not be vented.

That's weird i can see the picture fine, any way yes it show's the same routing of the vacum lines, i did actually have mine running that way at first also per a local import shop telling me (valve connected to bottom port and top vented) and i will tell you it climbed and climbed but i also had no adjustment with my boost controller until i rerouted it like your picture shows.
