Bumping this thread - did you ever figure out an ideal way to perform the boost leak test?

I plan to make something this weekend to do it. I do have a small air compressor, so i am thinking of making something like you did but with a regular air compressor quick connect, which will connect to the flexible rubber section of the intake tube (I think that is circular?). I would then set the regulator to ~15psi and check for leaks.

The only other thing i have read is that i will need to remove and cap the port for the vacuum line that goes to the 8AT.

I searched through a ton of boost leak threads but most of them were just people posting questions without answers, so i welcome any input if someone has DIY a pressure/boost leak test on a N55 8AT.
