Unscrew the little brass jet tip and drill the 1/16th hole to 5/64th. Replace and that burner is now converted from 16,000 BTU's to 20,000 or 22,000 BTU's.
Safe and easy. I did it to my Wolf stove years ago and finally got around to doing it to my Rangetop. The low, simmer and medium settings still work just fine, but you'll get big juice on high.
It's great to have one very hot burner for Wok cooking, boiling big pots of water for Lobster or Crab, etc.
