My 008 only gets to about 245. I have cooked ribs at 240 instead of 225 and there's not much difference except in time. I start my ribs, close the door and don't open again for 4 hours, no spritzing or anything. At four hours I can decide how much longer they need to go. I then put the ribs in a pan. Baste them top and bottom with some butter, honey and a little apple juice concentrate. I may or may not cover the pan with foil depending on how the bark looks. When I think they are ready, give them a bend test and go from there to eating or letting them go a little longer.
