So while 'window shopping' on american muscle, I saw SCT put out a new tuner called the x3?

I thought the big deal with SCT was the livewire....when that came out i didnt really hear much about it...then all of a sudden i saw this....same price as an xcal2...

does anyone know what the difference is? is it really just to include newer ford models? I dont imagine the parameters could really effect anything differently on our cars.... i'm happy with my xcal2, just wondering cuz i never even heard of the X3
