Hi there,
you cannot adjust the throttle body for performance. You can go to a throttle body spacer, which are dubious at best for making horsepower. The TPS is not adjustable, and unless you have need for more airflow, an larger throttle body would not help you much. Have you modified the vehicle in other ways?
