The Bosch Hybrid is actually a very good ignition system. It is normally only let down by poor plugs and/or leads. Spiral wound leads are a must, and a set of NGK 'v-type' plugs.
Was the ignition system hooked up to an oscilloscope while it was on the dyno, or is it just a guess that it is the ignition letting you down?
Has the dizzy been graphed to suit your engine?, as I think it would need something other than a standard curve with your HP.
If you want to change, then I would suggest a 6-series MSD. Take the cover off the side of your dizzy, and disconnect the Bosch module. Run the pickup coil wires directly to the MSD, and from the MSD back to the coil. Now, choice of coil....... what's your favourite colour?
Obviously, this is just my opinion........ I am not claiming to have built or set up countless numbers of 4.1L Falcons.
