The injectors supply fuel at the request of the Air Flow Meter: so more air,
more fuel. The oxygen sensor  adds its second opinion after the fact and all
is well.
A turbo or supercharged motor makes more power because it is being stuffed
with  more than its natural capacity of mixture . At 5psi of boost, Darryl's
motor is  using 30% more air, the equivalent  of a 2.7 litre or so.
