I installed the Savannah Stoker 3 on my lil Tex a couple of year ago, it regulates temperatures well, really well, probably too well. Temp swings are very minimal and as such smoke generation is lessened. It is my secondary pit now so it doesn’t get used much anymore and I’ve been meaning to tweak it to increase temp swings. I would say unless you are having real problems with your stock controller, or just want to tinker out of curiosity don’t bother.
