Frank,
Ignition breakup usually occurs under high load, high rpm - and unlikely in the scenario you're describing, boost pressure, ignition system you have, etc.
What it sounds like to me is an overly rich condition caused by too much throttle accel fuel. Are you setup to log wideband O2 on the street? Should be easy to confirm.

The motec has expander module with direct fire to 12 plugs...this should be sufficient?? What were the symptoms of "ignition breakdown"?
