Exhaust vs fuel questions

Hoping someone can explain from the bottom up something for me

The standard map from the DJ site for a Lazer exhaust (slipon) appears to dump in a fair amount of fuel all over the map in comparison to standard.

Does this mean this slipon is very free flowing and requires all the extra fuel to compensate for this reason?
More air and more fuel mean more power? or am i barking up the wrong tree?

On some of the more performance exhausts their maps from the DJ site there appears to be less fuel added. Does this mean the exhaust is less free flowing?

How does the flow of the exhaust vs fuel added/removed relationship work? Is there one?

Maps are generally aimed at maximising performance. But the bike manufacturer tunes for fuel economy, emissions, noise and general road rideability. Whether you need to go rich or lean really depends on how the stock bike was tuned.
