What spring for tial BOV I am getting ready to order my bov and was wondering if anyone has experience on to correct spring pressure a mild cam LS1 would use 7,9,10 or what. This is confusing me about this psi-vacuum thing. I should mention this will be on a street drive car every now and then. Or is there a way for me to figure this out . Or is it better to have a lower pressure so it will blow off easier.

18-21 vac= 11psi spring
14-17 vac= 9psi spring
10-13 vac= 7psi spring
I would guess you would need the 9psi spring
14-17 vac= 9psi spring
10-13 vac= 7psi spring
I would guess you would need the 9psi spring

I've got the 11psi Tial BOV and I think it is open at Idle though it closes as soon as you touch the gas. At first when I put it on the waste gate still rattle snaked at the same time the BOV opened but after about a week of normal driving with some quick hits the BOV was the only thing opening on shifts.
