Default Multiple Tees into manifold boost line, need some insight

Well,

this kinda got me worried and I thought of asking.

I just figured out that I got a bunch of tees on the intake manifold boost line, and a few on the brake booster.

on the manifold line, I got a tee going to the BAP pressure switch, fuel system pressure switch, fuel regulator boost referance, and finally the 2.5bar MAP sensor, which is mounted externally.

Then on the brake booster line, I got one connection with three joints, two going to the dual wastegates and one to the blow-off valve.

Im concerned about the accuracy of manifold readings with too much tees at least in the fuel system, boost a pump and MAP lines. I can't seem to figure out which has a more critical function for me to prioritize, but even if I did, what can I do about the rest?

Make a manifold. I like to use extruded rails and the drill and tap for fittings.

If you have more than two aftermarket vacuum lines, a manifold is the best way to go. Multiple lines installed at the same point is the same as 20 strings of Christmas lights plugged into one outlet. It looks like an eye sore and can be dangerous.

lol, this made me laugh... Sounds like my engine bay...

My WG, MBC, meth control unit, boost gauge, etc. all work fine... The one thing that didn't work was my BOV... It would not pull it at all... That's the one thing I gave a dedicated line to and now it all works PERFECT.

Google "golden eagle manifold". You'll need to get some little npt adapters and drill out however many holes you need, it works well for me. I have my boost gauge, Hobbs switch, and a couple other things hooked up to it.

OKay,

but suppose you use that splitter from one vacuum line for all sources you need, filling all or most of the ports... Would everything work okay? I've personally noticed some things don't mind being shared, like boost gauges and things that just need to read pressure to do their job... But would it be effective from things that need a good pull or push, like WG's or BOV's?

I would do mods and change pulleies and gain boost and a day later lost most of it, I talked to one of the egineers at procharger and he turned me on to one of their manifolds it goes in the brake boost line and I installed it and my boost went up, because my valve would stay open under boost. I picked up 4 psi.
