Requires recalibration for use on other vehicles

"Calibrating" a MAF for injectors is not the correct way to tune a vehicle, this must be done through ECU tuning. A MAF shoulld be chosen based on power and airflow requirements, and not sized for injectors.  For a vehicle to run properly ECU reprograming is required any time a different MAF is installed, please check with your ECU Tuner for MAF requirements.  This MAF is good for up to 500RWHP with its electroncs, and can be extended with a MAF Extender and or MAFIA for up to 1000HP.
