Thanks for the credit Smokie, but I probably learned it from someone here like Cheez. To pass on what I shared:
Typically, when I am going to use the Guru, I will open both intakes and the exhaust wide open. I will go ahead and attach / turn on the Guru and get my desired temp set. Then I will get the flame thrower out and start the coals in the front left of my basket. Once those are started, I push the basket in and close up the door. I watch the temp and when I get about 25* from my target temperature, I completely close my second intake (the one not attached to the Guru). I also close the exhaust down to about 1/3. And finally, I close the baffle or what ever it is called on the Guru fan to 1/3. Usually when I get to temp, I reset the Guru. I have read that this helps with the Guru's algorithm.
