Koehring 6625. Slow Hyds

Hoe seems to be slow when working. I've checked my pilot filter An washed it out seemed ok. Pilot pressure was round 500 psi. An all my Hyd fictions seem to be all around 3800 to 3900 area In witch is a Lil high for machine. Maybe I'm just use to newer machines.
Only running just lil over quarter throttle. Don't wanta Jack rps up too high. I'm not ready to start replaced a lot more of them expensive 4 wire one inch hoses. Them babies seem to cost ten bucks an inch Lol
