Why did you unplug it?

I don’t know about all the white smoke. A lot of people unplug the map with no problems. When I did it my truck didn’t like it, sent the truck into limp mode.

My question would be also, why did you unplug it...
some of us with the jeep liberty crd in the stable unplug the maf sensor to shut down the acv and the egr to stop the hot exhaust and soot from going back into the intake....

I think the idea is to fool the system into giving more fuel early to build boost and smoke more. The Edge EZ takes over the fueling and supposedly fools the computer into believeing there needs to be more fuel. I don't know how it keeps from setting codes and runs the rest of the time, though.

White smoke is raw fuel going out the pipe.

When you reset your codes which ones did you get?

You can only unplug the map sensor if you have a boost fooling box such as the edge comp, it will dump tons of fuel in at zero boost. Poeple still get mixed results and codes once in awhile WITH boost foolers.

Unpluging it with a stock truck will throw a code and the truck will run like garbage

The Edge EZ is a boost fooling box, so as long as the EZ was still connected to the harness going to the ECM, you won't go into limp mode.
