I put in a small regulator with guage at the gun, or on a QC adapter for the hose end if you're running multiple guns. That way you run your main regulator at 90, but can adjust your pressure at the gun to what you want when flowing. Takes the guesswork out, and it was like $10 at the auto paint store.
