Have any of you guys running JBD's noticed your urea DEF being used quicker?

also i'd like to know exactly what the JBD does too. Does it up boost, inject more fuel?

Would a better intercooler help a diesel since it relies on compressing the air in order to ignite the fuel wouldn't a hotter air temp be better than a cold one or does good dense cold air still help it?
It is my understanding that most of the gains are a result of increased fuel delivery. However, the boost was also increased although it was minor.

Terry/Mike feel free to correct me if I am wrong.
