Isn't the beauty of MAF over SD is that MAF isn't as sensitive to camshaft changes (vacuum) making them a natural for this? Or you can keep stock SD with a chip. Not saying MAF is perfect- just better at dealing with cams that have more duration than stock- like a 5.0 Mustang with the EEC4 system for example.

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.
