How to check DV isn`t leaking

Evening! after reading an article of "recirc dv (diverter valve) vs. atmost dv" i`m wondering if a dodgy dv (mine is standard) could be causing my boost to bleed off now i`ve upped the boost to a bar (was putting it down to a cracked wastegate housing before).
i flutters a hell of alot when releasing boost and sometimes make a more hollow sound when i let off after giving it some for a while.

any ideas on how to check if the dv is working properly?

cheers in advance, ollie
