Most likely the spring in the dv is too weak and letting pressure past while on boost
-
-
Could it be that the spring is too hard, needing a strong vacuum to let it open?
-
i've just bought one, looks like i've got some reading up to do to see which spring i need to use
-
you'll need a softer forge spring
-
If it helps i had a Yellow Spring in mine......`97 V70 T5
Held 20psi easy on 16T and then 18T

I'm running the red spring on 25ish psi and is fine, more chatter less air loss
