Thanks for that writeup, I just misworded the sentence about the residual pressure valve, I knew it just help pressure and not provided additional pressure.
As soon as I can find a helper and some sunlight here ill check the flow at the various points and maybe find some loose roads or wet roads to test on.
The MC is definitely higher than the calipers but not a ton, sound like I should probably just get rid of this prop valve and put on an adjustable one and a couple residual valves as well. Ill let you guys know how it goes when I can get under there with a helper.
Thanks a million again!
