yesterday my turbo swapped 2.2 was running great...i took like a 45 minute trip and on the way back home the bov was fluttering when i hit boost and let off. I have a brand new hks bov that has been on for 2 weeks. in the first 2 weeks i had zero problems with it and now all of the sudden its acting up.

Any thoughts?? my clamps are tight and i cant find a vac leak it just randomly occured on the way home

 

well...i was gonna say vaccum leak but you have already ruled that out.
