Yes, the stock ignition may be just fine and possibly can't be improved. I'm simply doing some research to see what could be done and what results may be obtained.

One other thing about MSD CDI system is multiple sparks below 3000RPM, my car currently has a lean mis-fire if I bring the AirFuelRatio to 14.7 at idle. This is most likely because I have non-stock cams. The sweet spot for best idle is AFR at 14.2 and timing advanced 7deg with RPM set to 920RPM, I achieved these settings by altering the Idle Fuel and Ignition maps in the chip.

So, would multiple sparks lasting for 20degress of crank rotation help with this lean mis-fire? not sure but I think I'm going to try the MDS 6 ignition as it is very non-invasive to install. But I do have a few questions to ask MSD Techs. Like will the timing be slightly retarded because of a delay caused by in-lining the MSD 6 between the DME and the stock coil. I think the answer may be no, if the MSD CDI simply fully charges the coil ahead of time and then removes the ground from the coil based of the DME ignition signal. Of course I'll also be testing this with a timing light.
