I cranked it up to max on my Prius shortly after I got it. Ran it like that for a few months but it seemed to cause the headlights to die young so I let them back down to about 40.

Then I replaced most of the lamps with LED and pushed the pressures back up to 51.

I don't know what the differences are between the truck's lamps and the Prius', it doesn't seem to affect them at all. It runs at 45. Any higher, though, and even I start to become unhappy with how the truck rides.
