Yes it's a 3/4 ton with factory hydro. I didn't think about changing that valve limiting the pressure to the booster. I'll have to give that some thought. I ordered the hose and plan to change things over this weekend. I guess I might as well give it a try since I have all the parts. If I don't like it, I can put it back and try to fix the EVO.
Just out of curiosity, has anyone ever tried to fab a rack and pinion into a GMT400?
