We all run rich because we assume that air flow is not equal to all cylinders.
If we were building race engines that had to develop max power with the highest possible economy, we'd flow the intake and heads until everything was near equal and run an afr of 12 - 12.5 because that's where max torque is made, regardless of whether the engine is turbocharged or not.
