I'm having problems on a docket with lift and lower moving very slow. So far the pump has tested good (2k+psi)..it tested at 1kpsi on the lift side of manifold. I have swaped all liftrelatevalves with a known working truck. The speed is set to high through the computor. Also I swapped check valve and counter vabalence Val es
Anyone have any ideas on what else to check..I'm thinking possibly the manifold itself has an internal leak
