After you’re custom barbecue Pit has wormed up for about 30 minutes you’re stack damper should have already have been opened. To make adjustment buy opening or closing the fire box damper to reach the the temp you want. Do not go make more than one adjustment at one time. Make an adjustment wait 10 minutes for the response. You can close the stack damper slightly on some Barbecue pits to actually get more Draw this works much like a fire place with a chimney damper.
