The problem with temp advice is that most vapes aren't accurate, and that's certainly the case with the OP's vape. And with the Extreme, the manufacturer has changed the heat sensor location several times, making the display temp vary from one version to the next, even though the temp is the same, internally. The best way to use any vape, temp wise, is to find the low and high end of the vapor range, for your particular draw speed, since that's a temp factor for most direct draw models.
