Yes, I am definitely not convinced on this one. At the end of the day detonation is detonation, irrespective of the strength of the spark.
neg:
OEM (Stock) plugs are fine on stock and remapped cars - no real 'need' to upgrade them - just swap them more often than normal if remapped.
As for altering the timing, this maybe so but you need to do some data logging to make sure your not making the ECU pull the timing back too much - all about the CF values and keeping them low.

I have never really understood heat ranges, What does a colder plug mean?
