Both threads solved...
RallyCV I wanna thank you for being a real sport on both of my threads. My other thread was solved when I was in the middle of installing my MBC today. Found an intake manifold nipple with a torn plug on it (torn through by a sharp hose clamp). Found that out while installing my boost source hose for my MBC, although it was not the MBC I had originally planned to use or install. I bought an awesome air pressure regulator for $25 from Tractor Supply over here and hooked that to the WG top port. I did this because I didn't want to put too much stress on the wastegate diaphragm while it was releasing pressure.I also disconnected and plugged the vac lines to the boost control solenoid and left it elec. plugged in. The result is a perfect idle every start and 15 psi of regulated boost. Right where I wanted it. I'm happy as hell with the install but want to melt that crap Voodoo MBC down for scrap. Big piece of SH#T. It might work as a check valve if $20/ea. is in your price range, though. Rally you can see the setup in the pics. Thanks for the help.

Hate to revive a old thread but im very curious as to what you did with the lines that went to the WGFV i see the one that goes closest to the connector goes on one end of the air pressure regulator, and that the other is going directly to the intake manifold, but what about the third hose? Just block it off or did you route it somewhere i just cant see
