BPV not venting properly

[Broseph09]

About 2 months ago I put in the Cobb XLE bpv and it was working great, it would vent pretty loud when running it 50/50. About 2 weeks after that I upgraded my fuel pump internals (autotech) and after getting everyhing back together my BPV makes barely any noise when venting now. Between me and a couple other friends we have gone completely through everything that we know could cause it. Checked all the piping for cracks and being loose and found one cracked vacuum line but replacing that hasn't changed anything. Everything else seems to work ok and there's no other different noises in the turbo spooling or anything. Any help on this would be greatly appreciated, thanks.

Not familiar with Cobb bpv but if you and your buddies already checked the obvious reasons why it does what it does after the upgrades, I suggest remove everything (you previously did/added) and re-install. There could be a chance that you might have missed something.

Also, make sure that the boost solenoid nipples are not cracked/broken (or not attached properly) from the inlet pipe.

I would look into lubing it up. My forge needs a good lube job about every other oil change
