I think passive regens are an urban legend!

The thing here is a matter of definition. Active regen is when the PCM commands excess fuel into the DPF to burn out the soot. When the engine is operating at a level where there is less oxygen than fuel, it will soot. (heavy load with low boost for the engine rpm and load) So when you have your foot in it hard, it is going to active regen more, because more soot means more plugging and more of the PCM stepping in and doing something about it. Passive occurs at mid level loads where there is a surplus of air and still enough exhaust heat to burn off the soot. The PCM has nothing to do with it.
Basically there is a fine line between right foot positions where too little or too much will lead to more active regens. But when baby bear is just right....
