Less fuel & less air equals less power. Lean/rich conditions vary depending on the tune parameters and is adjusted via the MAF readings. If there's less air flow, then there's less power...more airflow, more power. The A/F ratio is not something static in electronic fuel injector engines since it can vary the amount of fuel. This is basically why people eventually need a tune. It gets pushed beyond the stock map when they add bolt ons that increase intake and exhaust flow.
With a turbo for example, you're pushing more air and in and the ECU will tell the injectors to dump more fuel.
