That sounds right. You don't have a kink in the return line anywhere do you? I would suggest you put a manual gauge on it and verify the fuel pressure. It shouldn't be fluctuating like that, for sure. You might try running the truck with the gas cap loose to see if maybe the fuel vent is plugged up, if you find the fuel pressure readings you're getting are accurate.
