I have a 1997 turbocharged LS motor; there is only one vacuum source on the intake manifold. If I T that off to 4 more ports using standard Ts, does that decrease the strength of the vacuum pull?

I need that vacuum source to tap into: a 3-bar GM map sensor, fuel pressure reg, and wastegate. I just want to make sure it will get the right amount of vacuum pull even though it is only coming from one source.

 

I had posted this in FI also and got the answer I needed. Mods can delete this thread if they wish.
