Yes,the MSD box was not happy at all with it. Sounded like it was on a rev limiter before it got to 2000 rpm. I would have to let Rich explain it,I can only guess that the Firecore system has a long hot spark and and the coil won't take quick short spikes like the MSD. But as I said,that is purely speculation on my part from what I have seen happen with some other combinations.
