I have read a lot of these threads and I am getting the feeling that it is very hard to get temps up to proper cooking levels in a charcoal grill with offset smoker box. I also have read several threads on mods that can be done to help even the heat out. I have extended the chimney down to grate level and constructed a fire box. On the next smoke I am going to use my digital oven thermo through a tater on the cooking surface to better gauge my temp. My first question is will additional mods (baffle and tuning plates) help to increase the temps in the cooking chamber? Second, will raising the firebox above the air opening of the offset side provide better air flow and in turn increase temps of my fire to raise chamber temps?
