Actually Jim Wolf Technology does something similar to this for the
twin-turbo 300ZX. The stock setup uses one MAF for both banks. The JWT
setup puts the MAF to the left bank/turbo only. This cuts down on the
restriction. Obviously they re-map the eprom accordingly. Perhaps something
similar could be done for a single inlet system by creating a fixed bypass
and recalibrating around it. The stock sensor isn't a huge restriction at
low hp levels, but more is always better.:)
