Vacuum on throttle bodies?

[Nytro270]

Alright so I have a question for all you turbo savvy people out there, should I be able to draw a vacuum on the lines that appear to go to the throttle bodies? Would like to know before I go pulling the intercooler off to look for leaks

I would assume you would be able to. there is a couple of lines that go to the map sensors. should be able to get a vac signal from there.

yes my boost guage is connected to the nipples at the throtle bodies and reads vac untill it is under load alos vac when i let off that is how the blow off valve works it gets vac from those lines to open.

If you're looking to add a gauge, you may have to "T" into all of the throttle bodies, connect them together and then run it to you're gauge though. Didnt do that on one of my sleds a few years ago and the gauge fluttered around at idle. They'll pull a smoother signal connecting to all of them.
