I talked to MSD tech at dragweek a few years ago. I was having problems with one of there boxes and he recommended I close the plug gap from .035 because there was no power in it. I closed it up and it still misfired but he was very clear that the more gap you have the harder it is on the ignition pieces. I solved my ignition troubles by running away from MSD.
