I purchased a Pressure tester/Adjustment kit Any tips? 2100 PSI good starting point? BX25.

So I tested the Pressure after warming the machine up for about 15 Min and running the loader and back hoe though its motions, I got 1,800 PSI. I put in the 2 thickest shims and it jumps to 2,200 but then settles right down to 2,000 PSI. I was looking for 2,000 PSI but am I supposed to go by the reading it spikes to for a second or the one it settles down to.?

Just a note of WARNING! ;-)

I put an after market three spool valve on my Hurlimann 435. I could tell right off that the over pressure relief was set lower on the new valve. I considered bumping up the relief pressure.
About when I was getting ready to do so, I was using the loader to dig out a stump and wouldn't you know....

I broke the front axle casting!

I have not even considered upping the hydro pressure to increase lift or break out after replacing the axle. That was a lot of work!

I watched a few videos of people adjusting there pressure and theirs seemed to climb steady to max pressure and not go over, Mine does go over by 200 PSI briefly and drop. I Don't think that surge should cause an issue but I am curious why mine does it.

It is more twitchy more noticeable with the backhoe.
