also remember the larger the pv the eailier the pv will open,so earlier your in rich ment will be example, a 10.5 will open before a 6.5, because as the throttle opens and vacume drop's, and your running 15g's as you can see as the vacume goes down, it will reach the 10.5 before the 6.5...You want to split it in half or sligtly above.. if your running 15 at idle, half is 7.5, or a 8.5 depending on the rest of the setup
