Yes way too low, hopefully you haven't toasted a ring and broken a ring land. Is it tossing a code for a misfire? I would scope the cylinders before doing anything else. If the low fuel pressure already broke a piston you don't want to run it till the engine fails. You could try replacing the fuel filter and see if it helps the fuel pressure. I wouldn't go WOT unless you are in the 55 or higher on the fuel pressure. Those rear cylinders break very easily and QUICK. How do the plugs look on those cylinders?
What do the fuel trims look like?
