Hi Éric,
I also tried to make a huge scale billowing smoke and had a hard time trying to get the smoke to move more near the source.
I ended up using a trick!
The trick was to move the source in the fumeFX box instead of having a static source trying to push the smoke. And after the simulation is done I animated the fumeFX box in the opposite direction to cancel the source animation. The result is a smoke that seems to be emitted from a static source but I can add variation to the motion in the smoke by varying the animation of the source. To cancel the animtaion you take the animation curve of the source (remove it from the source), reverse it and apply it to the fumeFX box.
This way of doing a sim is far from real life but the result is closer to reality.
