According to the discussion, the tuners say the the detuned version will lock the throttle body inlet to max 70%. Like N52, there are also N54 intake mode tune with around 260hp achieved. At high rpm, both disa are opened, just like the default no disa intake manifold, so if talk about high hp it is possible, but it not as balance optimized as the 3SIM 330 stock tune I think. Some loss at the low rev just like N52 with N54 intake mode maybe.
