New best with my 340 Duster

The Crane and Daytona I consider good. Most of the MSD not so much.

It comes down to how well the ignition can get the burn started. The development of the flame kernel is critical to how the burn proceeds.

All I know is I have had multiple boxes fail, and every car I have installed the Daytona Sensor box and coil in, just runs so much better and ETs are better.
