How accurate is a pressure switch?

[lilflippy]

Just bought a new pressure switch its comes factory with it turning on @145psi and turning off at 175psi

So I install it and looks like its about 5psi too low....turns on at 140psi and turns off at 170psi...

Should I adjust it or leave it alone?

I'd leave it alone. How do you know the gauge is accurate?

My thoughts as well.

Think about it...if your gauge better than 5% accurate, it's a pretty accurate gauge.
