Yes. My buddy has one of those electronic sensors used to test AC heat--we checked cooking level left, right and center. The thermometer that came with the grill was at the top. When the top temp was 250, the left (next to the heat shield) was 235, the center was 225 and the right (next to the smokestack) was 220. a 15 degree differential which is acceptible. That's with a pretty decent fire in the firebox. Before the mod, the same fire would have the top thermometer pushing 350-400. That was WAY overheating even at the cooking level. This mod fixed that problem but good!!!
