Best way to figure what BOV spring is needed? Im going to a whole new setup as in sig.. Guess when I do the startup on the base tune before dyno, I should just see what vacuum Im pulling with the new cam. Then by the appropriate spring off tials reference chart before bringing to dyno.. Any input on this??

Spring to Use
- For Engine Vacuum Reading Range: -22 through -23 Use: 12 PSI
- For Engine Vacuum Reading Range: -18 through -21 Use: 11 PSI
- For Engine Vacuum Reading Range: -14 through -17 Use: 9 PSI
- For Engine Vacuum Reading Range: -10 through -13 Use: 7 PSI
Do you know what your vacuum is? I have a spring or two for the Tial 50 that I'd let go for $10 plus shipping. I'll have to go see which ones I have but I KNOW they're not the 7# because that's what's in there now.
