Dom,

When=20 running a mag and the Light Speed EI they recommend the timing be set on = the=20 mag with a timing light as they do for their unit as well. If the shop se= t the=20   mag timing with a buzz box that could have changed it. I run the s= ame=20 set up. I get almost no drop in rpm when the mag is shut off. This is due= to=20 the fact that the mag mostly sparks in the shadow of the longer hotter=20 sparking electronic ignition.

I=20 would retime both the EI and the mag and see what you get. I have the hal= l=20 effect module and you use a simple automotive timing light with marks on = the=20 fly wheel.

It is=20 pretty easy to do..

 

FWIW..
