He never see a an injection... Don't speek about compressed air injector.

Not just fuel control, but a _good_ efi is big improovment in
driveability. And some races jus forgot, the good driveability is more
importatn like few percent more peek power.

 Ok for oval/drag ( a la USA) not a big issue, but for real tracks...

For high power output, the injectors are half meter far from ports...

for high rev engine the efi is better. You can set up carbs for igh speed,
but your engine died at low. With efi, _should_ be both.
