a chip is installed inside the ecu which changes the air/fuel mixture in the engine, also will advace or retard ignition timing to gain power
this resistor just makes it think it has cold air, so adds extra fuel as cold air is denser, so tries to stop it running lean, but it causes it to run rich instead
