This may actually cause more problems... with the injectors above the
throttle butterflys, the air is moving at a higher velocity past the
injector (better atomization)  if you put it below the throttle plate,
distribution and atomization would likely suffer... if you want injectors
below the TB, port injection is best... Because you're not injecting into
the plenum, the flow is higher at each port, and the timed shot can be
spraying as the intake valve is opening, causing better atomization and
control.
