Doesn't pilot-wave QM imply literally the exact same calculations happening as for MWI, though?

No, it doesn't. Pilot-wave QM postulates an additional fundamental equation (the guiding equation) that doesn't appear in MWI. It describes how the behavior of the wave function affects the positions of particles.

Okay, so it does some extra calculations. But it still does all the same calculations as MWI?

Yes, it does all the same calculations as MWI plus some more. The only way to empirically distinguish MWI and Bohmianism is through anthropic considerations (like in the quantum suicide experiment discussed elsewhere in this thread).
