Mine goes from 12 to 13.1, that is if .1 V is even possible.

ALternator comes to mind first. I had a weird one: The output cable was bad and kept killing the voltage regulator.

I did that for a few months. Expect your alt to crap out soon. Worse case scenario: You blow your electrical system from an overload. When you rev and it adjusts the voltage it may mean the voltage regulator is dying/faulty. It COULD ZAP your electrical system just as easy as it undercharges it. Keep an eye out and test the voltage at the B-terminal.
Learned most of that from RETed.
