I've never had a therm on my grill. I may do the mod to put one on. My only guess is that maybe try keeping the lid parallel to the ground and only move it off enough to put your stuff on. That may hold in more heat. I typically never pay attention to what the temp is and just cook food til its done, but I may start paying more attention to up my game.
