How much boost are you running with it?

It just might be the wrong spring stiffness

IIRC, unscrew the BOV and pull out the spring. There should be washers stacked inside. Play with the number of washers inside until you get the desired result.

What he said.


I think 2-3 washers would be about right.

Yeah.


Try just one for now. I have 3 in mine, and I'm at about 20ish PSI.


What do you have the vac line hooked up to?

If you can describe the noise it's making a little better...


I wonder if you don't have enough boost to make if go off all the way...


Try it with no springs.

the sound sounds like the air is getting stuck in the mass air at the top of the motor , i'm getting mad, i think that there isn't enough pressure/ boost to move the spring what other options do i have?

No.


The spring is what prevents you from having a massive boost leak.


Just call Turbo XS in the morning.


Also, I'm not trying to be a dick, but you need to read this.

haha that's a good one no i had 2 different bov's already they worked fine this one is giving me a headache. Blow Off Valve Type H-RFL (BOV-RFL) is what i just purchased.. if i used the throttle from under the hood and kept turning the bov do you think it might eventually tune??
