what should the operating pressure be for my 2k4 AC?

I'm using a Blackmagic HPR inline, and a Ninja 68/45 with the lower pressure shim ( I believe 500psi). Should I change the shims in the tank so it 800 or so psi or will it be ok with that 500 input?

Once I get the tank sorted out, I'm adding a gauge to my front block, what kind of pressure do I want to see there ?

You generally want your input pressure to be twice what you will reduce to.
If you are using stock internals you can expect your ideal operating pressure on the autococker to be 300-350psi.

If your tank is outputting 500 it is a little on the low side, but probably just fine. My ninja tank actually outputs 600 with one shim, so not every tank outputs the same with identical shims.

I have CCM internals in it.. It could be 600 I'm not exactly 100% sure, you're probably right.

so once I have the HPR set to 3-350ish I then adjust the LPR to where it will consistently push the back block back and cock the marker?

I haven't had an autococker in ages.

Usually 300 PSI for CCM.
Read the attached manual.

Once you have working air in the marker hold your trigger down and turn up your LPR until the bolt is all the way back. Then bump it up a little more. You can fine tune your LPR later, you just want it working while you chronograph.
