Do you only have these large temp swings while cooking at higher heat? Do you have the 25 degree swings while cooking at say 220? I found my Ironwood 885 will swing more with high temps. Not sure why, may be because it will dump lots of pellets in and then once the pellets ignite the fire roars? I never really pay much attention to temp swings unless the app is giving me low or high temp warnings or if I'm trying to cook something low and slow. Id say watch it and see what happens with low heat cooks! Also, do you have a welding blanket for it yet? It will also help if you dont...
