I've often wondered about the nuances of inlet tuning and the helmholtz resonators that we see. My guess, and without running testing with pressure probes it will remain as such, is that the helmholtz resonator chambers only impact accoustics. While the chambers do act as temporary accumulators I don't think the pressure waves of the helmholtz chambers are significant to the pressures seen at the intake valves. It may be significant on exhausts as one can run the helmholtz chamber to deaden sound without killing off pressure with a standard muffler, but inlets don't make 'that much' noise so no need for restrictive mufflers.

Some intake design stuff including some basics on intake length and helmholtz theory.

So with the TRD CAI, or other system, the intake runner length / volume / diameter are all being tweaked so the 'peak' may be tuned slightly but I doubt you'll notice a loss of any low end.

Apparently the LS7 (corvette engine) removed the resonator chambers.
