The subject pretty much asks the question. I have the twin chamber BOV and have had the screw very very loose and now have it very very tight. With it real tight it doesn't seem to release boost that fast. How tight should it be on our cars running 10-12 psi of boost.

Thanks,

Go to www.apexi-usa.com for the instructions on how to adjust it.

I have those instructions. They don't help for ****. I had the car running and took the screw entirely out and the car never stalled like it says. I just need to know the ideal place for the screw to be for our boost levels. They say the screw should be tight for high boost levels and loose for low boost levels. What are they considering high boost levels, 10 psi or 20 psi?

Did you stock BOVs go bad? There is really no need for the BOV unless you go to single turbo.

Well considering I already own the BOV , it is a little late for that kind of a response.

Anyone else?
