2013 f350 6.7L.....Not sure yet, but this MAF PID data might be a 'substituted value', not the actual live sensor data, but a value the PCM/ECM just plugs in as part of it's default engine protection strategy.....that can really throw off the guy trying to diagnose it. But it could also be an air leak or something else. Will find out.
