Fuel Pressure ? ? ?

I just installed a electric fuel pressure gauge. Having read before that the stock pressure is around 53 psi, and some are "adjusting" the fuel pressure via shimming or regulator to 60~70 psi.

I have a TS Performance chip and Garrert GTP38R turbo. I no fuel system upgrades (regulator/ fuel system return/ injectors) and my gauges reads ~60 psi on idle/ light load. It will drop to ~50 psi under WFO.

Where do I need to have my fuel pressure set?
Higher than 60 psi?

So with that being said, I need to have my truck idle @ 68 psi, correct?
