One thing, I am measuring the temp at either end by having put themometers through in either corner of the chamber door. I may have them too far apart, meaning measuring at the extreme ends of the grill. Just a thought. Maybe I should do the whitebread test instead.
Yeah, there are a lot of variables in this stuff as far as heat displacement. With the deflector, the stack extension AND the tuning plates you aught to be getting the heat where it should be in the cooker. The only other thing that I can think of is making sure the airflow is good and moving easily through to the exhaust stack.
