Thanks Mike, Dwain & Rich.
Yep, I've stalled at 155* 5 hrs in!! (Shoulda kept quiet).
It was nice and steady up to about 125*, then slowed up.
I have a 6lb-er rolled pork shoulder in. Gonna let it ride till 160*, foil it, then hopefully get it up to 190*.
I've foiled the pan, no water. I'm sitting steady at 230*.
Again, thanks for your time/advice guys.
Tony.
