How does the mass airflow sensor work on a new car?
The stock mass airflow sensor is designed for stock tuning (air and fuel flow) and will not automatically re-calibrate for additional air flow. Upgraded intakes can lose power with newer cars because most use MAF-based fueling. With a change of pipe size, the fueling is affected, and the factory ECU is calibrated to the stock size.
