Why Edge? Go SCT Xcal3, the power is night and day. I've had both.

The Xcal has those safety features. I'm not sure about the delayed shutdown. I would contact DJ's or Innovative and tell the them what you want your safety parameters to be. These guys are awesome tuners and they can keep it as safe as you want while giving you much better power.
