I get this sound at 5000 rpms. And it's only when I let off. I just swapped out the old bov and I still have the sound.

If the car wasn't drivable - I would help a forum-member out and drive the 20 minutes...

Hey, if it is not with the bov (since you've swapped back and it keeps happening), and most likely (not certain) is something else. Did you check if your vacuum line (thin hose that goes to the top of the bov) is free of leaks and its connections tight? Anyway, it couldn't hurt to open the bovs and take a look if they're clean.

I can drive it, I just have to take it easy and stay off the boost.

And thanks!! Glad I joined this forum.

Thanks for all the help guys! It means a lot!!!
