How to drill you PS pump output oriface... This is a must do, without it your steering will be hopelessly slow.

I tend to disagree with pressure mods. The system is designed to run at ~1500 PSI, and going above that just puts undue strain on things without making a significant difference. Instead, consider a larger ram (if in fact pressure is the issue). The proper size of ram will depend heavily on the mounting style. It's all about the leverage.
Bobby, what size ram are you running, and what throw does it end up using lock to lock? Pictures?
You might also verify you running pressure... Not easy, I know, but I've got a little guage you can borrow if you can get it plumbed into your system.
