I just received my Sct Powerflash Tuner with free CAI from Late Model Resto.
I thought that I was getting an X3 but I recieved a SF3.
They look like the same tuner just a slightly different decal on the front.

Is one better than the other? What are the pros and cons?

SF3 comes with tunes on the handheld from SCT (3 preloaded tunes).

My understanding is that the X3 is for tuner shops - to load custom tunes on (up to 3 custom tunes).
