Solid explanation......thank you.At higher boost levels (17+) there is allot more cylinder pressure than stock. That higher cylinder pressure actually tends to suppress the spark. So, to make sure the fire gets lit and ignition is consistent, a smaller gap makes it easier for spark to jump the gap.
