I have the fuel pressure sensor and datalog function working well on my setup, but it is roughly 2psi difference than my other FP gauges. From my research I'm seeing that the default setting is for a 0-5v sensor, and not the 0.5-4.5 sensor I have.
Is there a way to change this in tunerstudio, or is my only option to pick up a 0-5v sensor?

You will need to edit the INI file to match your sensor's output curve.

Re: 0.5-4.5 fuel pressure sensor
Am I in the ballpark area I need to modify? This is under the "output channels" section
fuelvolt = { fuelADC < 1 ? 0.0 : fuelADC * (5.0/255) - 0.5 }
fuelpress = { fuelADC < 1 ? 0.0 : fuelvolt / 0.04 +1 }
This is what the default setting was, any changes I made didn't have an effect, so I returned it back to what it was originally
fuelvolt = { fuelADC < 1 ? 0.0 : fuelADC * (5.0/255) - 0.5 }
fuelpress = { fuelADC < 1 ? 0.0 : fuelvolt / 0.04 +1 }

Just us the custom gauge wizard in Tunerstudio, does all the work for you.
