my sct has custom tunes???

Ok I bought a truck from a guy about three weeks ago came with the edge juice setup and he through in the sct tuner with it as well, I asked him if it had any custom tunes he said no. Well today I was loading the sct and went under custom and there was three tunes there I think agrressive tow, street and aggressive (130 hp) are these custom tunes??? I loaded the aggressive and wow that thing kills the edge setup.

So does anyone know what tunes these are? They were under the custom file on my sct.

Could just be the can files that come on the sct, as I know they come with 3 tunes when you buy them.
