You don't,  the ECU compensates for minor modifications to the intake and
exhaust tracts that increase air flow volume and velocity in and out of the
engine   i.e. mandrel bent exhausts like Remus, Techtonics and P-Flo,
Q-Flow, or the AMS intake filters.  Higher levels of engine tuning that
include cams/intake manifolds, superchargers, turbos, or nitrous or even
increased engine displacement would probably require upgraded injector,
fuel pump, fuel pressure regulator, and/or ECU (chip) tuning to ensure
correct air fuel mixtures.
