Before I jump head long into this, I'm looking to see if there are any 2005-2009 S197 Mustang 3V Centrifugal supercharger files available for download to look over and study. Since I don't own a HP tuner yet, I can't get into that section. I'm not asking you to post any actual files, just an idea what's available.
It might tip the scales to me doing nothing if all that's available is a single cai s197 3v file.
It's like, "hey, buy our product then see if there's any help available".
