A P0300 OBD code indicates a random or multiple misfire. If the last digit is a number other than zero, it corresponds to the cylinder number that is misfiring. A P0302 code, for example, would tell you cylinder number two is misfiring. Unfortunately, a P0300 doesn't tell you specifically which cylinder(s) is/are mis-firing, nor why.

Do you have any symptoms of any misfire? If not try to reset and see if it comes back.

I know a lot of the misfires in the 6.0 had to do with the electronics of the injectors. Mostly in the 03 year and some 04. Not sure what is causing it, but I can't imagine the SCT causing it but anything is possible I guess.
