what did you unplug? edge reads boost from map sensor. You need to plug the map sensor back in.

Is the edge harness directly plugged into the MAP sensor? Another fooler in the circuit may cause the problem. If you have just the edge harness and the factory harness plugged in, it may just need a battery disconnect and sit for a bit.

I assume the factory harness is plugged in as well? If so, there could be an issue with the Edge itself.

With my Edge I have the Edge harness plugged into the MAP sensor, and the factory boost harness plugged into the Edge harness. It's all working for me, no boost fooler.

Sounds like your factory plug for your map sensor is not plugged in. mine would not build boost till it was...
