Default Wideband Install Question

Planning on installing a wideband soon. I was curious what bank (driver or passenger) runs leaner?

The passenger side should run leaner, as it is farthest from the fuel pump.....in theory.

Neither, under part throttle. The PCM will adjust both sides to run them where it want's to.
Under WOT, it's in the tune as to how much fuel gets through the injectors.
