Slow Lift with no codes

Raymond 560-OPC30TT

-Check control handle potentiometer voltage
-If voltages are good connect a pressure gauge and check for 700 psi
-If pressures are good a good culprit for slow lift is a bad proportional valve

Its 2000psi when the mast stages but just to start it 700psi until it get loaded up. I compared the pressure reading with two known good units and they all came out the same.

At least 2000psi. Not 700.
