I have a 2008 Mustang GT and the fan seems to always be running, can you please advise what the stock thermostat temp is, and what I need to raise the values by so the fan doesn't run constantly?

The factory fan settings should be Low at 196 and high at 210.

and I take it the 91 Octane tune is set lower and that is why they run constantly?

Well, this isn't a common complaint, but I would recommend going into the "modify parameters" section and adjusting your fan settings to your liking.
