I think the multi-spark only occurs up to around 3k RPM. Any of the MSD boxes are higher energy output than the Bosch or PermaTune. I think the StreetFire is something like 95 MJ and the 6AL is around 110MJ.

More spark energy, like more spark voltage, is NOT a measure of performance.
Again, once the minimum spark energy is achieved, any additional energy is wasted.
With regard to; "My nose says the fuel burn at idle was improved (less rich smelling)",
most likely the fuel mixture was not set correctly and "smelling" hardly suffices for
a CO meter.
