Yea 60-70 is usually preferred. Maybe your FPR is clogged up? Dirty FF? Clogged return line? Hard to tell
A RR, fuel cross over, etc. is not going to lower your fuel pressure. It allows fuel to flow THROUGH the fuel rail, THEN to a FPR which allows for more consistent pressures as well as to let any air pass through. It allows for adjustable fuel pressures but you've got another issue I think.

I too was curious as to what the pressure should be.
After installation and startup, I looked at the frame rail under the driver's side and took a picture of the pump. I assume that this is the stock electric fuel pump?
Yes, that is the OEM pump. There is only one, right there under the driver's seat.
