Dom,
When running a mag and the Light Speed EI they recommend the ti= ming be set on the mag with a timing light as they do for their unit as wel= l. If the shop set the   mag timing with a buzz box that could have ch= anged it. I run the same set up. I get almost no drop in rpm when the mag i= s shut off. This is due to the fact that the mag mostly sparks in the shado= w of the longer hotter sparking electronic ignition. It is my understanding= that the Electronic Ignition is doing 90% of the firing of the gases in th= e cyl.

I would retime both the EI and the mag and = see what you get. I have the hall effect module and you use a simple automo= tive timing light with marks on the fly wheel.
It is pretty easy = to do..

FWIW..

Dom,
I'm sure the most common cause for this is a = change in ignition timing.  I assume the mechanic left the Lightspeed = system alone, but did the normal routine of resetting the timing of the mag= .  If the two timings are exactly the same you will likely get the sam= e drop on each, or maybe a little less drop on the Lightspeed.  I've o= bserved that most annuals include resetting the timing, but rarely will the= mechanic state what it was before the change, which would be very useful i= nformation.  I'll bet he advanced the timing of the mag by maybe 2 deg= rees.  Just a guess :-)

Been wonderi= ng why. Changed my iridium plugs two days=0A ago just as a starting point b= ut no difference.
 
So thought I would ask the experts herein.
