Problem solved, this morning we changed the check valve caps from 10 psi ones to 4 psi ones, after the initial charging of the booms the sprayer didn't move 5 feet and all the nozzles were spraying uniformly even though the controller hadn't locked in on 20 gpa it didn't take it long to regulate and it would maintain 20 gpa from 3.4 mph to 6.5 mph. i was actually able to maintain this with the pump slowed down and the throttle valve maintaining 50 to 55 psi on the pump side of the valve instead of 65-70 psi, if i slowed the pump just enough to get 45 psi on the pump side of the throttle valve then i could slow down to around 3 mph and still maintain 19 to 21 gpa but that lowered my top speed to around 4.8 mph. Yesterday i was about to give up on this system but now it working fine for us.
