There are some that still run stock ignition, but most have gone to a CD ignition such as MSD, ACCEL or Jacobs. I'm not sure that they really give any HP advantage, but the increased spark energy is nice especially if you've increased the compression ratio significantly. A custom burned chip is OK, but really doesn't gain us NA guys a whole lot; usually less than 5HP.

I can't think of anyone right off the bat that is speed density. Everyone is Mass Air which lets us go with larger MAS, injectors, etc.
