our city water supply is at a really high pressure (over 150 psi) so I can
set the pressure regulator for any pressure less than that

I like really strong showers, how high can I go without reducing the life
of things?

If you go to high you take the chance of blowing out your copper sweat pipe
joints. Think of the cost of replacing copper joints in a wall somewhere.
Not to mention the water damage caused by a break.
