Performance modifications do not produce advertised gains unless your vehicles computer has been properly tuned to match the new airflow characteristics of the engine. For example, aftermarket headers actually over-lean a vehicles air / fuel ratio and actually can reduce performance until your vehicles computer has been calibrated properly.

Dyno Tuning

Dyno tuning (as mentioned previously) is where the vehicle is put under load and tuned according to the engines needs in various situations. Dyno tuning allows you to correct computer tables for timing, air and fuel while testing engine modifications for the best possible combination for your particular application.
