well i just went outside to mess with it.. its at the softest setting and i even went as far as to remove one spring. this causes it to leak because i feel air coming out the bov and i still here the rattle ..
its comming from the air filter thats on the turbo so yeah its gotta be compression surge.. my only other thought is that i have the profec B spec II the wastegate the boost gauge and the BOV running off the same vaccume ...
could this be the problem ? not enought vaccume to work the bov so its not opening fast enought to release pressure? maybe i can shorten my vac line? or tap into another line ? any ideas?
