Actually mafs before 99+ work and need the pigtail. IIRC the pigtail maf plug changed in 96. I run a 98 mustang gt meter (I think they are the same as the cobra like our 94-95 gt is the same as the cobra).
I have a post in the tuning section with the whole transfer and a graph of a few transfers to compare. Search under my screen name as well as setting the search to look only in the tuning area.
