Depends on the car. On my vehicles, it is designed to regulate to about 90% of the pump pressure. Not much reserve left. It seems like most cars would be like that, I mean why would the manufacturer put in a lot more pump than is needed and increase cost?

I built an adjustable circuit once to trick the O2 sensor into leaning the mix. It leaned it out all right, but when leaning it out it also killed FE.

Other cars may vary.
