Bill,

How often do you change your plugs?  Often enough to avoid SAG?

I had my power drop event, but because of the conditions I'm not sure
it was SAG.  D581 Coils and about 10 hours on 100LL.

Also, I don't think we really KNOW that the high power CD system will
avoid the problem.  Lynn doesn't use leaded gas in his race cars as I
recall.  I"ve also wondered if the MSD Blaster coils were really as high
power as the MSD CD system Lynn uses.
