DIS vs Individual coils

[Bruce Plecan]

On turbo applications running high boost/big cams has anyone
here actually had a problem with not being able to retard the
timing enough to make max HP, due to an intake tract popping
occuring?  ie lighting the open intakes AF mixture.
  Not with oem cams, but longer duration aftermarket stuff.

Other than for individual cylinder timing control is there any reason
to go to individual coils?.
