Boost reference points?
Where else can I get a boost reference off on the plenum. So far I have my gauge, wastegate andBoV all T-ed off the port near my MAP sensor. Now I need to add my FMU and would like to put it on its own port.
Where else can I use?

You could always drill and tap a new fitting.
BTW I haven't forgotten about you, I just have to look through the boxes I have for the item you seek.

Yes, just use T fittings installed in the existing vacuum lines. The FMU needs only a very small intake manifold pressure source, so you don't need a dedicated port (just make sure all the connections are solid- I use zip ties to make sure the vac hoses don't come apart when under boost- if the hose comes off the FMU while you are supercharged, you may go lean and end up walking home). Most FMU's come with a restrictor to install in the manifold pressure refernce hose.
