    I think the consensus was that at high RPM the multiple spark is of 
no advantage over single spark.   I agree; the MSD 6A on my car only 
helped idle quality and low RPM performance.  No noticeable difference on 
the high end (but no detriment either).

    While we're on the MSD subject, I can't get a tach to fire off my 
6A box.   No signal out of the tach connector.   Anyone ever fix these?
