Great mod job! As for the 425* reading, when the fire is roaring on an ECB, side mounted thermometers read the heat coming around the water pan. Mine read 100* higher than a digital probe on the grate under these conditions, almost the same once it settled in. I took mine off and mounted it in the lid.
