Altitude definitely changes compression pressure. My shop is only a few hundred feet above sea level.
If you have less air (lower barometric pressure) to start with, then your final compressed pressure is going to be lower. Your 60 psi sounds healthy enough, but you will be down on power vs. sea level.
