The specs put it between the Digital 6 and Digital 7 by MSD.

Gives 530 volts to coil vs 570 for the 7 and 450 my the 6.
The millijoules are more in Digital 6 range
but the current draw from the battery is only .7 amps vs. MSD's 1amp for guys with no alt getting hot lapped in final rounds and costs far less than a MSD 6

sounds like a good option for a lot of cars who don't have the compression and high octane needing a MSD 7
