I think arnworx has a procedure written up for testing intake system.

Smoke testing the intake makes finding leaks alot easier but pressure testing works just as well. You just need to make a PVC fitting with something like a tire schrader valve on it that fits into one of the intercooler pipe couplers. You can test at the turbo inlet aswell if you wanted.
I hook up a spare boost gauge up to the intake manifold so i can easily monitor pressure. You usually dont need much more than 10psi or so to hear any leaks. I use a tire chuck to control how much air i am letting in but a regulator would work just as well.
This adapter is from Arnnworx, not sure if he still makes them but it works well. Just becareful when using something like this as its not totally impossible for it to blow out of the coupler.
