I checked my factory pressure setting and it was sitting dead on 2200psi.
Pulled relief valve and shims. After measuring some washers I found one that should have put me right at max factory spec. of 2410psi. When checked after install of washer, it now has a max of 2500psi. Should I leave it there or try to bring in back it down to 2410psi?

The oil was warm and the throttle was maxed.
Thank you for your help.
