Make sure valve is open all the way and the pump head is pushed all the way down before locking down.

This is incorrect. All the presta pumps I have do not give the correct pressure reading until I begin pumping.
noobs: What pump do you have? What kind of tires do you have? 80psi is pretty low for road tires, despite seeming "rock hard". For wider tires, 80psi might be adequate, but it depends on what type of tire you have.
