Pressure you can adjust with a spring on the discharge port of the pump. Flow is a function of displacement of the pump. A hydroboost and a rack will take more flow than just the rack.

I'd run the type 2 Saginaw pump that came on your LS motor first to see how it works. Is there any LS motor that came in a truck or car that didn't have a rack and pinion?

Off road cars running the LS Saginaw pump often use a ram steering setup and there's higher flow Saginaw pumps to meet the higher demand of the ram steering.

If you need more flow, you can buy a bigger pump from Howe Steering and several others. LS trucks have a different steering pump shaft size than cars do, so be careful.

They also sell different pullies for the Saginaw TC pump that will change the flow rate.
