This did bring to mind a question -- This car has no MAF sensor, so it does not sense air flow directly. How does the ECU interpret a restricted air intake? For instance, if (heaven forbid) I mash the pedal to the floor, the throttle position sensor goes wide open, but the intake tube, being slightly smaller than the TB opening, is not allowing quite as much flow as would normally occur under stock conditions.
Does the ECU take into account engine vacuum
and other factors to compensate for the reduced air flow? This will never come into play in normal driving on this car, but I was curious about it.

yes
it uses a MAP sensor as the primary load sensor
MAP = Manifold absolute pressure
MAP = ambient barometric pressure - intake manifold vacuum
the system is in fuel control so a slightly restricted air intake
has about zero affect on anything
except at WOT
as per EPA and iatn
