I did it to the maf on my 99 silverado with the 5.3 however you have to be careful not to damage the elements inside of it. Some people had problems with their engines after removing it so it appears to be luck of the draw. There really isn't any improvement with the stock maf by removing the screen so your best bet is to leave well enough alone. If you're wanting a performance increase buying a superchips or comparable tuner is the single most cost effective upgrade you can do.
