That happens when you use a spring that is too strong, and you have to "adjust" other valves, the only spring that should be used is the yellow spring. It's not that hard to even change the spring, screw off, screw on.

yeah, stock one has been back on for while, im glad i didnt drive around too long with the hks unit.
why did you buy an aftermarket bov, they just cause problems unless you really need it because your heavily modded. put the stock on back on and your car will drive better and be faster
Ill tell you why i bought an aftermarket. Because im an idiot. I love the sound. Thats it. I dont even know about the positive effects for the high mod bracket. I just love the noise. That sounds so low brow but that the reason. That sound alone is worth my $250. Sounds stupid and maybe it is, but thats the sound i want my car to have. I will do what ever it takes for the car to have that sound. Thats the thing about cars to me, its not just the HP or the torque, it the look, its the sound, its every thing. The car as a whole is the goal for me. I dont really care if i can smoke everyone that comes to call. I like good race. I dont care if i can out bump everyone that rocks my mirror, i like a good bass off. My car is my own and there is much more than functionality. It is my #1 concern, but there are things that i will pay for, (like my system) that will slow it down that im okay with because they add more to the overall experience for me. And thats what matters, is how i feel about the ride.

All I know is that either one of two things are the cause of this...one, you installed it completely wrong, or two, this HKS is faulty. Either way I would get it replaced. My HKS is in perfect condition and is operational besides the fact I am heavey modded...

Tell that to the second gen DSM owners.
I think I saw somewhere (on here) that the stock BPV has a tendancy to leak. So that leads me to believe a new BPV would be a good buy. And the HKS is just the muts nuts.

The stock bpv "may" rupture during high boost.

I would say somewhere in between. Plus, it obvioulsy won't rupture running the stock maps.

If they are the same BOV's used in Supras, I'd say the HKS SSQV isn't exactly the best choice. An independent test showed they were dog-slow and caused ripples all the time. If I remember correctly, their racing valve was far better, and Blitz made a great one too. IMO, Forge doesn't have it quite right, either. Too much trouble with springs and shims, and some people seem to complain that they can't quite get it dialed in. This is like trying to get momma bear's porridge, if you know what I mean. As far as I know, the HKS and Forge both have more issues then its worth. Do we have other (recirc) options?
In the supra world, the Bosch BOV used on Porches seemed to be a great alternative. I loved mine.
What issue, use one spring, the yellow one.
I don't see the problem or issue.
Forge said:Valve Spring color coding
Green - 5-15 PSI
Yellow - 15-23 PSI
Blue - 23-30 PSI
Red - 30 + PSI
I don't see the problem or issue.

Ask around, this isn't universally agreed on.
I know, but there shouldn't be any debate, the yellow spring should be used and nothing else. More tension makes the valve harder to open(increasing lag, not opening at low boost, etc.)Ask around, this isn't universally agreed on.

If actual usage shows that the blue or red spring performs better for the application, then why should there be no debate?

I think you mean the stronger tension has a less chance of leaking boost so that means more boost(power) As long there is no compressor surging you will decrease any boost lag with a higher tension spring.

EEK. This is what I was talking about. How about a valve option that doesn't require this adjustment? Example: The Bosch BOV I mentioned. Plus it was $45 at a Volvo dealer!
Also, what about the new version of SSQVII?

well i just installed my ssqv last week n propably that fluttering is due to a leak of air on the flenge... i noticed this cuz my car was running slower ... less pressure.... so i checked out n adjusted n it fixed this... that little ring tightener on the flenge should be very tight spo no air scpaes... now idk bout recirc it should sound different
