About a year ago I replaced my stock DV valve for a Forge 007. I installed it and for the first months it made this small swoosh sound, it was awesome. Now it doesn't do it anymore. I checked the top nipple for any air leaks and I found nothing wrong. Why doesn't it make that sound anymore? I installed it both ways and I didn't hear any difference in the sound. Greased it like the instructions said after a year. What can I do? Is it even working? Thanks

If you are boosting correct, then it is working fine.

~7-9psi for k03
~11psi for k03s
~20in vac at idle
~25in vac cruising foot off throttle

Well I don't have a upgraded turbo. I do have a aftermarket exhaust and it is chipped. I was told in previous forums that I should be putting the yellow spring inside.

Yes, put the yellow spring in it. It does not grant you more boost, but will hold it better. The green spring will tend to have your boost curve surge. The yellow spring is rated 15-23 psi.

Green:5-15 PSI
Yellow:15-23 PSI
Blue:23-30 PSI
Red:30 +
