Engine Tuning:

Experience higher engine performance designed to meet more power and provide the best balance between performance and emissions and dynamic handling characteristics.

Detuning And Downgrades:

Detuning is the process returning a modified car to its original factory status, or reducing its performance in a particular area of tuning. For example, a car may be "detuned" to allow increased traction when the track grip is not sufficient to handle the increased power of the tuned engine.
