Yeah, I'm not one to get too terribly upset about a temp swing. I ended up pulling the fattie off and forgot to get a pic first. Every time I pop the lid on my UDS, I get a pretty big temp spike, so not gonna open her back up just for a gratuitous pic.
When I pulled the fattie, I forgot to close up the air intakes first, so that made it swing up to about 320 again. But she is slowly backing down again.
It's actually cooking a bit faster than I thought it would, it's at 158 internal right now, but I'm guessing the stall is likely coming soon.
Now I'm off for taxi duty for my son's baseball practice this morning, followed by a quick stop home and then basketball practice this afternoon.
