okay so i have a d15b with a 50trim turbo. my vac lines are fine, pushing 22vac on my boost gauge. and im running 8psi on the streets. but basically i tested it with two different bov's my knockoff greddy type-s and turboxs. both wont make any noise i just hear the wastegate any ideas? im running the bov to the vaccum manifold btw which comes from the brake booster and intake manifold vac.
