Did a filet last night. It was 32* and snowing (we had 6"). B380 under the porch roof. 1.75 inch thick steak, smoked at 275 for about 30 min. for internal temp of 127*, took it off and wrapped in foil, then cranked the pit up to "riot" and in 10=12 minutes or so the temp rose to 812*!!! I opened lid for 15-20 seconds, and lowered it and the temp gradually went down to 751 and remained there. I put the steak back on for 45 sec. twice on one side and twice on the other to get the sear marks. Result was a great steak that was about Medium. But what impressed me was the high temp achieved in short time with 32* ambient temp. I think the 812* was an initial overshoot that would have corrected without my intervention. I have noticed the 380 doing that with lower settings. First an overshoot then a gradual settling to the preset temp.
