i had our 02 at our cabin this spring for 2 weeks and it is at 7000 feet. i had no issues with my 120v compressor. ran normally.
as for adjusting on off of the compressor psi, all it is is a common square d well pump switch. i dont think they make many of them you cannot adjust. you can take the gray box cover off (after the power is turned off for the compressor) and if there is one screw with a nut on it, that is the one you can adjust the cut in psi. they mostly have a 20psi differential so if you adjust it up or down the differential of 20psi remains the same. if there are two adjustment nuts, the smaller one adjusts the differential.
i would more wonder if the lower temps at altitude are exaggerating any air leaks you might have. or were you using more air for any reason?
although, i am not sure why you would want to adjust the pressure.
