990 power beyond questions – Green Tractor Talk

I have a 2005 John Deere 990 tractor that i want to run a hydraulic powered saw off of. According to the dealer, i have 8.5 GPM available, and I need 7. I bought the parts for the power beyond from my dealer and installed them. My saw works, but I’m not getting the GPM I need, The saw should be running at 3200 rpm and is only running at 2200 rpm.
