The ID of the vortech bov vaccum line is 1/4", but I have it running to a 2 way barbed fitting then to a 1/8" vaccume line then to a 1/8" vaccum tee(On FPR) I'm wondering if this could cause any problems? It definitly sounds different now. I just don't know which vaccum line to tee into that's 1/4". I thought to use the PCV valve one, but then figured that would cause some problems.

 

so u have an adapter that goes from 1/4" to 1/8"? does it kinda flutter when u close the throttle?
