With the car off and the CV in place (so it should be piping straight from IC to WG), should I be able to build pressure / vacuum in the WG line ? Should the WG be sealed ?

I'm unplugging it at the IC pipe, and blowing into it. There is basically no resistance.

I am getting boost control, so it's not completely venting the WG, but I wonder if I'm losing boost somewhere.

If the CV isn't shut on the bleed line, you won't get any resistance blowing into the IC end.

Which one are you calling the "bleed line" ?

There are three ports on the CV:
IC - Intercooler
WG - wastegate
JB - J boot

When it's not powered, it runs IC-WG, correct ?

And under power, IC-JB ? or WG-JB ?

When it's not under power and it's running IC-WG, should you be able to pressurise it ?
