In this video, we take a look at the common practice of using a
"Calibrated" mass air meter (MAF) on a Foxbody Mustang with and without implementing a custom tune on the EEC-IV computer. The major issue relates to load calculations, which will impact both fuel and spark in a SUBSTANTIAL way.
To be clear, there is nothing wrong with such calibrated meters. In fact, my experience with many of the units coming from Pro-M is that they are very consistent in quality and accuracy... some of the best out there for these applications. But using them without a tune is really just a band-aid.
