Help please

So the coupler on my BOV tore off lastnight. Not a huge deal, but I replaced the coupler today, not hard. Now when i drive it sounds like I have 2 BOV 1 when i let off the gas (normal) and then a few seconds later it sounds like a less aggressive air release, but im not sure where its coming from.. Do you think there is a leak with the replacement coupler, has the BOV gone bad? anyone have an idea?

i did lastnight when it tore off, but not since i replaced...

I think i need to check the throttlebody to ensure the O-ring is still there, it turned upside down when i was maneuvering it and i didn't even think about it till now..

i hope thats it, either way im buying the Stett or RDS tommorrow...

might want to get a boost gauge as well.

try a Qtip after that, you might just be hearing things.
