I have the attitude that if your going to run a Mopar then run a Mopar, don't try and Band-aid it with a GM ignition module which is really not much better than a decent Mopar ECU they all perform the same way and are not designed to fire today's fuel formulation. GM modules read a much different voltage signal than a Mopar box and as we found out the reluctor clearance and cranking RPM make a huge difference in the voltage output to signal the control unit and mixing them up is going to create issues when things aren't perfect. To me it's like putting an LS1 in a Barracuda or running a Power-glide transmission behind a 426 Hemi... I just don't like it, I'm a Mopar Guy I can't help myself.
