Ok guys, I have a question for you guru using guys with the lsg cabinet. I am in the middle of my 1st cook and am having a little trouble with the temperature control. It took quite a while to get up to 250 using the guru and the ball valve open. It got to 250 and I shut down the bale valve to closed and closed the damper down half way. It could not hold temp there by itself with the just the fan, and it is a 25 cfm fan too. I had to open the ball valve up to get it back up to 250. So my question is how do you guys have your ball valve and exhaust when using the guru? Do you guys even use the other air intake when you use the guru? I have the guru on the pipe closest to the door and the ball valve on the back pipe. Thanks
