True: MAF systems are more tolerant of airflow changes Cams/heads etc than speed density due to the main fuel calculation is related to the O2 content coming across the sensing element Both systems works if you can get a consistent A/F that meets your needs.. Just that MAF has some quirks that can mess with tuning if you don't know whats going on.
