My jeep does the same thing. Don't know why you need to rev past 4k in neutral but to each his own.

Chicks dig it when you rev that 3.8L muscle.

First thing that came to mind was limp mode, but if you have an auto and it is in neutral then I would say its built into it to prevent people from blowing the engine while trying to look cool at red lights
