I have a 7747 w/ $42 mask, this seems to be the most common by far, but yet discussions on even the best sites, with the most helpful folks (y'all, 3rd gen, IFSJ etc...) can be confusing because sometimes they refer to TunerCats, sometimes TunerPro, and everyone has their own definition files so parameters are called different things. I've seen the same parameter referred to as a "max" value in one .xdf and a min value in another! Yes, 1project2many this could be a "how to tune".
Once upon a time Custom EFI's started a tuning handbook that attempted this. I have an early copy so it's largely incomplete and in most cases refers to parameters by name as per his TunerCats .ecu file....
