I have done quite a bit of research in making my Mailbox Mod. The mod works just fine with my AMZNPS and the MES 40 on cold smokes. However, the other day I tried some ribs and the MES 40 wouldn't get past 200. Using the AMZNPS inside the MES40 is a little hit and miss even with the suggestions of microwaving, pulling the chip tray and loader out a couple of inches. I can usually get it to at least 240 if needed. Am I missing something? outside temp is around 70. The mailbox creates smoke just fine but temps around the 190's is just a little too low and slow. Suggestions?
