dont go too stiff a spring otherwise DV wont open much at all, and defeats the object of having it.
Green spring on mine was good for 22psi without leakage, so yellow is next one up just in case.
I'm running yellow in mine on 35psi boost no issue
Cheers Bill, so it might be running a blue spring thats the issue? I have a yellow at home I think, so will try that...
Thanks
Mike
