I wouldn't use an autotuner if you're going to be making excursions well outside of the antenna's stated range.  The tuner's ratings are for antennas that are already pretty close, but using 100 watts with a "300 watt" tuner, made by anybody, is about as much as I'd want to try, especially using an already-short antenna on 80M.
