BOV vaccum/spring question
I was told by the techline from this vendor that I was to measure the vaccum pressure at the line I was going to use for the BOV, and the divide it by two, and then select a spring that is SLIGHTLY higher than that number:
ie......if my vaccum reads 20, then I should choose the 11 psi spring.
HELP! I am going to use a vaccum line from the throttle body I believe.
