Why no Too Lean code in car with turbo/super charger?

Hi to all,
I am confused about turbo/super chargers air ratio going in engine.
Fuel ratio is controlled by mass air flow sensor let’s say when turbocharger send more air in engine, why there is no engine check light?
I mean there is too much air getting in cylinder so it should indicate a check engine light,
No?
Normally when there is air leak in engine, there is check engine light showing engine running too Lean code something... because engine is getting more air ratio than fuel, so why...
