I went to Super Autobacs yesterday and they had the SCT tuner for the 4.6 Mustang. I only did research on the predator with its larger screen than the SCT, but then again, that's all I know about it. I was wondering what the differences were (if any). I see that SCT only has a one line screen though the guy at Super Autobacs said that he prefers SCT because it's easier to program. Does SCT also allow for OBD-II diagnostics like the Diablo Predator?
