No, not exactly. Your hyd pump has a potential of, say 2500 psi. That is the available force as soon as the pump is running. As soon as you activate a cylinder, the pump starts building up pressure to the cylinder, and can be any pressure between zero to the pumps designed pressure. Some loads in your bucket will not take much pressure. If you raise an empty bucket, it might only take 800 psi to get the job done. If you scoop up and lift max load, the pressure might build up to say 2500 psi. If you should try and lift a load above your limit, the relief valve will relieve and protect the valve or cylinder. Just running the tractor at a faster rpm only increases the ability of the cylinders to work faster. You have the same force through out the tractor rpm range.

I would recommend installing a pressure gage at the input to the FEL valve, or making up a hyd test set including a 3000 psi gage, hose and fittings. You could also make it using Quick Disconnects, so you could just plug it in and read the pressure throughout the system.
