SupraD06 Posted November 19, 2012 Share Posted November 19, 2012 Hi guys, just a quick question about the vac line possision for a Profec B II Boost controller, and gauge. If you look at the picture below, the arrow in RED is where ive seen many other people plumb the vac line in, However mine was fitted to where I've marked it in GREEN. Is this ok? Or should i move it? Also the vac line that runs from where ive marked in GREEN, to the boost controller in the dash, has had a 'T' piece added that feeds a boost gauge. Is it ok to plumb the gauge into the same vac line as the controller? Any info would be great thanks Dave Link to comment Share on other sites More sharing options...

TBDevelopments Posted November 22, 2012 Share Posted November 22, 2012 its a direct feed from the intake manifold, you'll be fine Tim Link to comment Share on other sites More sharing options...
hodge Posted November 22, 2012 Share Posted November 22, 2012 As Tim says, and positive vac reference is fine. The reason people use the other pipe is it directly feeds the MAP sensor which gives the ECU it's boost reading. It's usually T'd into there so the controller is reading from the same vac source as the ECU. Yes it's fine to T your boost controller and boost gauge into 1 pipe.
