little bit more, can see 1.3 or so under full load at higher rpms.
I can hear them open when I let off the gas (swoosh)(I don't have much sound insulation). I didn't hear them open as often when I switched to the aluminum valves. So I played with my diverter valves with different springs and compared them with how much vacuum is required to open stock valves. Decided I liked the green springs best. Looking at the design, didn't think the spring would make much difference on how fast they would close (which I think is why people use stiffer springs).

I have some form of billet diverter valves on Rufus... old age (mine) prevents clear recall. What sort of symptoms might one observe if the valves were sticking before going to the bother of taking them off and testing them? My boost gauge shows a very normal boost pressure when expected. Thanks.
