My car been working great @7psi, but yesterday it started to cut at 4psi. I would floor it and my car would boost only @4psi. Another thing that sound different is the BOV. It deosn't make the psss sound, but more of a "loud air leak."
I checked for any loose vacumm hose, but everything is in place.
Is any of my component cracked?

 

are u sure u don't have boost leak check around the bov too to see if there are any leaks

 

I thought it was the BoV leaking too. But I checked and there's no leak there.
