These are facts, not debatable, and that is where most people fail to comprehend airflow and power in any normal gasoline engine.

There are absolutely countless examples of larger components being used, and low end power being lost. Absolutely every one of those examples shows a fool who did not properly tune the engine after the modification. Of course power is lost all over the place when the A/F ratio is moved from ideal, which is what most changes do.

The PCM must be reprogrammed, even after little changes, if you want all of the potential.
