Hello all. I am experimenting with my BTLE. I have made most of the mods ( minion box, extended smoke stack to grate level, 2 river country Thermos at grate level, and sealed fire box and lid. I also have a 16 ga tuning plate approx. 24" long with the last 6" bent at 45 degrees. The plate is pushed up against the end of the smoke box so heat is going underneath and around the top edge of the 45. I am still getting a 25 degree temp difference between the fire box end and the stack end. Any suggestions on what to do to get the temp up at the smoke stack end?
