To give a bit more detail on my process, I heat a chimney of coals until they barely ash on top. I put about a half chimney of unlit on the grill on the sides and back. I then pour the lit coals on top of the unlit along the sides and back of the grill and a few in the middle. Put the Kettle ring, stone, baking steel dome and grill cover on and let that come to temp for about 45 minutes until the stone hits about 550.
I then put in about 5-7 chunks of hardwood depending on size, I used hickory on the pie above. Let that go for about 15 minutes and the dome temp will hit about 900. I have gotten it as high as 1000. My pie then goes on and I bake for about 4 minutes, turning a quarter turn every minute. We like multiple toppings so with fewer toppings I would modify the cook time accordingly.
