Endeav, WG duty is an indication of the difference between the boost dme see and it targets, plus jb4 duty bias. Nothing else. It does NOT mean how hard turbo is working.

Dme usually see low boost with Piggyback, leading to high duty.

Boost target is a complicated thing, you can have underboost and dme is not even trying to close the gap, and have overboost and dme still pushing. With or without piggyback.

You try 24psi (your hardware can), it'd still do it and taper. See for yourself.

Anyway there is the whole N54tech board and the mighty Terry to ask, why didn't you? Also you can send me the log. Will see if I have useful input thru PM.
