For several years I had a medium BGE that I thoroughly enjoyed. I particularly liked searing steaks at very high temps, ~800 degrees. Last summer I sold my medium and bought a XL BGE. I'm having trouble getting it to these same high temps. I typically pile up the BGE charcoal in the center, and start it with my electric starter, but it gets nowhere close to 800 degrees. Even if has been completely cleaned out with the lower vent wide open and the upper vent wide open. I'm wondering, does the XL just require a lot more fuel (charcoal) to achieve these high searing temps?
