50mm tial BOV what spring?
50mm tial BOV what spring? My BOV is not working properly. I have the 11psi spring in it. My vacuum at a idle is 9-10. It shoots up to 15 when I let off the gas but the BOV does not open. If it is opening it is not fast enough because I can hear my turbo backing up. Do I go to the weakest 9psi spring? If I understand they way to pick a spring right than the 11psi should be working. What do you guys think?

Silver Spring: 12 PSI - (between -22 and -23 in/Hg)
Silver Spring: 11 PSI - (between -18 and -21 in/Hg)
White Spring: 9 PSI - (between -14 and -17 in/Hg)
Black Spring: 7 PSI - (between -10 and -13 in/Hg)
Im using the 9 psi currently. I haven't tried my 7psi or 11psi yet. I can't test because I can't put the car in boost (untuned on the meth), otherwise you could have my spares to play around with
Wouldn't the car just leak out of the BOV the whole time then during vacuum?

I called hp and they are sending me a spring that will leave the bov open all the time while in vacuum...
