i think you just solved my problem El Ropo. I started the UDS up this afternoon and put my digital probe on the cooking grate. Ten minutes after I dumped half a chimney on the coals the Tru_Temp in the side of the drum was at 150 but the Nu-Temp digital on the cooking grate was at 250. Within another few minutes it was at 367 so I capped three nipples and closed the ball valve about half way. Thirty minutes later it was holding around 350. The Mrs. and I went for a ride for about an hour and came home to the same temp. I put together a 2# fatty stuffed with pepperoni, pearl onions and cheese and threw it on with six 2" thick pork chops and all is well!
