Hello, New to tuning, not new to technology, cars, or DIY projects. I have been thinking about this for weeks and can't seem to find a definitive answer anywhere. Why run a MAF sensor? What applications does it help you and what are it's limitations (i.e. when would you be better off not using one?) Applies to all but I am planning to turbo a 5.3 and am trying to decide if I need to start looking for an IAT sensor or accommodate a MAF/IAT in my charge tube design.
