Vacuum Distribution Block Questions

Whats up everyone? I am getting close to finishing the EG build. Trying to get the last wiring, routing and details done. One of these details is a vacuum distribution block. I sourced the blocks vacuum from a large port on the Skunk manifold. The turbo I am using does not have a port in the housing so my initial thought was to source its reference from the distribution block. My concern is that the blocks source is on the intake manifold, after the throttle body. So when the throttle is closed will my distribution block still give an accurate reading to things like my wastegate, boost gauge, etc. I guess in a more direct way to ask this is if it is okay to get the vacuum/boost for these things from the intake manifold or does it need to be from the intercooler piping prior to the throttle body?

It should be fine to plumb it off the IM. For all intents and purposes the pressure in the lines is traveling at the speed of sound. There should be no delay or pressure drop unless you seriously oversize your hoses
