Find someone who lives in Denver in another area of high altitude - they'll probably have the highest stock psi levels you'll find. My guess is ~19psi is the highest anyone will see stock.
As for me I drive in an area where elevation varies around 700~900 ft above sea level. In the winter, I would see 12~13psi tops. In the summer, I'd say ~15psi tops.

Check it out:

Air Density at Altitude:
Sea Level ---> 1.225 kg/m^3
5000 ft ---> .736 kg/m^3 [Edit: This is actually for 5000 meters. oops. 5000 ft should be 1.055. Only a 14% difference.]
That's a 14% drop in air density. So the turbo has to compensate by pumping in a greater volume of air. 14% greater.
Temp also makes a difference, but not nearly as much: [Edit: Actually a bit more with a 100 deg change.]
60 °F ---> 1.225 kg/m^3
160 °F ---> 1.027 kg/m^3
A 16% difference with a 100 degree temp change.
