How do you test/ adjust plow pressure?

I have a Meyer E-60 on my 99 Dodge Ram V10, it was on the truck when I bought it. The truck and plow sat unused for a few years before I purchased them, so I've been spending a lot of time working the bugs out. My most recent problem is poor turning performance. The pump didn't have enough power to move the blade back when it was all the way extended in either direction. It went left and right OK unless I went to full lock, but didn't have enough power to turn when the plow blade was resting on the ground. It went up and down fine. I took the cap off of the reservoir and dumped out the old fluid and got out as much sludge as I could without major disassembly, and replaced a few o-rings/nylon seals. I made a pressure gauge and coupler setup to go in between the pump and the hoses that go down to the rams, and I was barely getting 200 PSI turning the blade against a tree! I removed the acorn nut and turned that adjustment bolt in half a turn, and that improved the performance. I kept adjusting it, half a turn at a time, until it was turned in almost all of the way, and I'm still only getting about 1,000 PSI. The plow performance seems acceptable to me, but I know something is wrong. So my questions are: Did I do the pressure test correctly? Is there another test or adjustment that I should be doing? My gauge goes up to 5,000 PSI. I want to check the "crossover pressure" that I keep reading about, but I don't know how. Any help would be great, thanks!

the E-60 should be up around 2500 psi the (E-60H should be around 2000) over 3000 things start to break from my understanding. Checking pressure with the angle lines is probably the easiest, but you can also test pressure from the pump outlet port (I think you need some kind of adapter to do that though).

you can also use the same setup to adjust the cross over relief valve
