"Test" them? Not particularly.
I had a set sitting around ant they are the regular Bosch coils that Microtec sells, which are pretty decent.

 

I used test only because you said the aem's are poop compared to the ls2 coils so whatever method you compared the two to each other using i wondered if you applied to the "ignition solution" coils. Bosch makes a set with a TTL driver in them which i believe would eliminate the need for an ignitor box....so i was wondering if the coils were weak as well as the ignitor box.
Just curious really as to how you tested and the outcome and if you included the mazsport system in your testing.
