What PSI in Walker Evans shocks?

Looking for what PSI I should be running in the stock W/E shocks on a 2 seater XP1000. I went through a violent high speed roll over this past weekend and now the passenger side sits about 3/4" lower than the driver side. I’ve looked and looked some more an cannot find anything that is bent in the front end suspension or frame. I’m wondering if I somehow blew the shock out in one of the flips???? I have a high pressure nitrogen tank from my rock crawler and was going to try and add some more nitrogen to see if that fixes the sagging.
