Forge BOV not opening!

Just installed the Forge BOV along with the ECP enabled tune from Trifecta. After building boost and letting off the throttle, I hear a fluttering through the air box instead of wooosh or a pssssht like you'd expect from a BOV. I suspect the BOV is not opening and the pressure of going back against the turbo (hence the fluttering). Any ideas why?

Do I need to install the yellow spring? No instructions came with the unit.

Ok, some a**hole *cough*me*cough* failed to reinstall the vacuum line and thus, caused the pressure to go back into the turbo and out the air box.

Not the BOV's fault, my fault.

Doesn't have a chirp to it. I'm going to install the yellow spring later and see what happens. The air release takes quite a long time vs other BOV's I've heard including my SRT-4.

Additionally, my wife made fun of it and said, awwww, it sounds so cute! :disgust (1):

My girlfriend said the exact same thing when i installed the K&N SRI, my face was exactly the same.

Let us know how the yellow spring is.

Must not have had lube on it?

That kinda comical Titan, lol. I'm glad you found the problem though.

I wonder if they'd ever just fabricate an adapter, so we can use ANY BOV on the market(Greddy, HKS, etc.)
Not enough room for a non replacement.

Titan also a heads up, the bypass will need to be serviced and you will notice a similar condition when you will need to relube the center shaft. This will propably not be for a while but listen for the same compressor surge and a tinny type noise. I usually do this about once a year before the colder months.
Yeah I noticed a lot of red stuff when I swapped springs. I assumed it was lube.

Re-lube with what lubricant?
Probably a graphite or silicon powder

stock bov kinda sounds like air release on a big rig LOL
Yep, drove past a bus yesterday and was like, aw man thats what I sound like :(
