The MAF Limit Extension modification increases the factory MAF scaling range, allowing accurate airflow measurement at higher power levels where the stock calibration reaches its limit. By increasing the measurable airflow range, the ECU can properly calculate fueling at higher power levels without maxing out the MAF signal.
