One thing is clear – the technical stuff on their website in nonsense.  For example, the 50 watts vs 1,000,000 watts of spark power. A Watt is a measure of power, energy times time; a joule/sec.  The coil delivers the same amount of power whether there is a regular plug or a PulseStar plug. What the over-priced PulseStar plug does is concentrate the power to a higher voltage, shorter peak; which can have some advantage is overcoming gap resistance; but doesn’t necessarily give better fuel burn.

 

The depiction of the pressure in the cylinder is also bogus – doesn’t represent reality in either case.

 

As someone else noted, it is very much the same as holding the wire about ¼” from the plug.  Back when I was a teenager I had a somewhat worn 1947 Chevy. The worn piston rings would cause the plugs to foul.  When pulling the wires to figure out which cylinder was missing, it didn’t take me long to discover that the pug would fire when I held the lead a short distance off the plug.  I found that using a short length of fuel hose that fit snuggly on the plug, and on the lead, allowed me to slip that on and maintain the gap. I called my invention the “gap adjuster”.  The PulseStar has a more reliable version of the “gap adjuster”.

 

It is possible that it could help with the SAG issue, so someone who routinely burns avgas may have to do the test (Ed? I know you love this kind of stuff).  Maybe instead of buying the $25 ea plugs you can devise a reliable “gap adjuster” and see if the SAG goes away.
