Im having strange boost problems. I have a lot of preload on my arm (about 9mm) and im running 12psi of boost. I turned up the boost using a bleed valve a quater of a turn and it's hitting 21 psi. I thought the bleed valve was at fault so i removed this and run standard actuator pressure. Its now 10 psi.

I have nothing inbertween 12 and 21 psi.
