There was a trick years ago for overly powered ford PS, cut both the hi pressure and low pressure hoses, install the appropriate sized "tees" in the middle of each hose, the middle of the tees will be the same size, put a small brass shutoff valve between the two as you open the valve it bleeds of some of the high pressure lines pressure to the return line and cuts the amount of power to the steering thus making an adjustable power steering so you can go from full power to no power and anywhere in between.
