Is there anything that one of these can do that the other can't. Like I hear the Diablo can turn off your o2 sensors. Can the Xcal do this. Also which one is easier to use and which can give the most gains?

I've always heard the Diablosport was better. But then again I've heard that the SCT Xcal 2 was better for GT's.

Do you know if either of them have features that the other one doesnt have?

Sorry I dont. I dont have one personally, I just kinda go by what others say about each.

I have had both. I liked the diablo because it had a larger screen, but I like the sct 2 because it can hold up to 3 different custom tunes and is faster loading the tunes. The sct is a must if your running nitrous or different size pullies on your supercharger. The diablo will only hold one tune at a time.

I've heard nothing but good things about both, but my local performance shop runs SCT software so if I ever need some help with the SCT X-Cal 2 they can help me out. So that's the route I'm taking. Mustang Tuning has them on sale for $380 shipped w/ the custom tune already insalled, then you can tweak it when you get it at your house...
