I was unhappy with the 20 degree temp swings on my Pit Boss Pro, so I installed a Smoke Daddy PID controller, fan, and auger, but the setup ran 30 degrees hot with the expensive new parts! I called Dan and Dennis for help and wound up sending it back for "re-programming." After installing the new and improved unit today, I tried smoking salmon. I wanted to start low, so I set the controller to 160. It climbed up to 187 and wouldn't come down. I wound up cramming a welding glove under the cover to release some heat and got the temps to within 13 degrees of setpoint, but still hot. Has anyone else had problems such as this? I wanted a Savannah controller, but no one had them.
