go to home depot and get a rubber vent cap from the plumbing section the size of the IC pipe going into the throttle body and a tire valve with the little nut you tighten down to seal it to what ever you are attaching it to. Drill a hole in the rubber cap, stick the valve through it and put the nut/seal on it.

clamp that bitch on the charge pipe as far up stream as you can (right at the throttle body). get a tank of air, or a line off the air compressor (when its not running) and give it a quick blast in the system with 30 psi or so. If you have a leak you will hear it pissing out and can track it down. or if you have a loose coupler you will blow it off. lol

$5 boost leak finder for the win.

BONUS FEATURE, put it on the throttle body and look for gasket leaks, vac leaks, etc. too!

This won’t work to do a boost leak check.
