You have the new gen 2 and the intake and exhaust are too small. Air flow is limited. You call pull out the chip loader all you like but if you don't give it somewhere to go it doesn't matter. You can dremel out another slot in the exhaust port to double your exhaust or pull out the vent completely and replace with a 5 dollar 3 inch adjustable elbow from lowes and put a rotating damper in. Pull your chip loader out so the opening of the holder extends beyond the smoke chamber opening. Helps get more air and flow and both the amazn tray or tube work fine. The air flow fix also helps with the tendency of the mes to overshoot the set temp. Along the same lines..... try using small chunks. They work great in the new gen mes. Longer lasting and great flavor.
