HELP!!! Tractor Problem!!!?

I have a Mahindra 4505-DI, I recently installed a loader on it, and the loader seems to not get enough hydraulic pressure, it is REALLY slow! However when I set upper limit stop lever, it seems to work properly. In turn, when I set it, my 3 point hitch fails to work. Is there I way I can set the hydraulic pressure so that I don't have to compromise the other hydraulics on the tractor, like the 3-point hitch? Best answer will be selected! Any and all help is appreciated.
