Excuse my ignorance but I know very little about BOV's. It is an HKS. I don't know whether you need to replace the spring or whether there is something you can just tighten. Yes, it does have it's own vacuum source I believe.
Please help!!!
Thx man,

johnny, if it's the newer HKS SSQV, there's no adjustment screw on there.
Did you mean it goes pst pst pst pst pst instead of pssssssssssht?
How many lbs of boost is it when you release? Mine does the same, when i let the throttle go at about 2lbs of boost, it does that. But when there's alot of pressure to release, it'll dump it out all at once.

I used to have a greddy bov and it was a POS it leaked like crazy after 1bar of boost.

Where did you get the BOV??? I just read an artical about immatation parts that are bought online and on ebay. The HKS BOV was one of the featured parts. They tested it and it did not perform well. I have the same BOV with no problems, pushing about 6.5lbs. It could be a fake.

Where does your boost gauge point to while idling?

IMO, ditch the HKS BOV... It is an inferior product to the TIAL BOV. I used to have twin BOVs pushing 30psi and those things leaked.... I then switched to a single Tial and all the problems were solved. Tial is hands down the best.

Guys,
I think the problem was an install error!!!I don't think he had the vacuum line connected properly so I was just dumping boost as soon as I made it. Hopefully dyno at the end of the week.
Seat of the pants is telling me that it rocks!! Maybe Joe (Sockfocks) can jump in as he rode with me tonight!!
