I know this has been discussed and debated a bunch of times. I just got a BBQ Guru (CyberQ II) and today I cooked a whole chicken. I had the placesetter in and put the pit probe next to my v-rack that had the chicken in it. I set the pit temp at 265 and the dome temp consistently read 220. Is this differential normal? I calibrated the dome thermometer so I know its accurate. The Guru operated and held temps exactly as it should have - the grate temp stayed steady at 265 for over three hours. I still have some experimenting to do with the Guru but just wanted a sanity check on the temp differential.
