I just picked up a pitmasteriq 110 this past week, and decided to give it a test run this weekend with 4 racks of baby backs. I had everything set up all nice, I had the iq therm right in the middle, and put in another digital therm along with a bimetal just to verify that this thing works like it's supposed to. One thing I noticed was the temp in the middle of the grate was actually lower than the outer edge of the grate. I knew something wasn't right when my digital was reading 250, but the iq had a flashing green light. I moved the digital to right beside the iq probe and that's when I realized it was only 235 in the middle. Now, since Im running 2 grates in my drum, I use a deflector/water pan so as not to run anything I put on the bottom rack. Just thought that was interesting since the middle is usually the warmer area. Once I moved everything around and got to the sweet spot on the damper on my iq, we were trucking right along at 240-250.
Only issue I saw was that you're supposed to be able to close down all the intakes and just use the iq, but I still had to open one intake along with toying with the damper. I noticed that the hose barb is 1", so I had to buy a reducer fitting to get down to the 3/4" that my ball valve is. Im wondering if that restriced the airflow enough to make me have to keep both intakes open, or if maybe mine just has to run with two open.
