I have hydraboost with a ram and it works fine you dont have to do anything to your pump.
remember that if you do mod your pump you will likely burn it up a lot faster than your stock pump and putting an underdrive pully on to speed your slow steering up will deffinitely burn it up. that comes straight out of matts mouth from wto.
he told me there will always be one down fall to this system
1. either your steering will be slow at an idle or
2. you can speed it up with an underdrive pully and it will burn the pump up much faster.
I chose a slower steering at an idle when you need it to turn faster touch the throttle.
