its the runners, the intake that feeds air to the engine, no sharp corners to cause turbulence, a swirl air flow that promotes better atomization when the fuel enters the combustion chambers. fuel cannot ignite without oxygen, which is a small portion of the air mass that enters the intake. tpi, involves fuel injectors that spray, a pulse of gasoline sprays directly into the cc as the piston is being forced upward, the valves are about to close as the piston reaches the top of the cylinder, therefore creating a compression stroke, igniting the air fuel mixture so the piston can be forced downward to produce hp and torque. the old carberators were less efficient but got us around... sometimes, rick

What does tune port injection mean?
Tuned port injection simply means that all the intake "tubes" are equal in length. This same terminology is used for exhaust headers, tuned headers have equal length tubes from the head to the collector that attaches to the exhaust pipe. That explains the sometimes crazy looking bends on them.
