Turbo Charger: Controls
Turbocharger performance has improved with the use of computer controls. The computer module monitors boost pressure, throttle angle, airflow, and more.
Early model turbochargers experienced turbo lag and hesitation. Today's computer-controlled turbochargers have increased performance, especially during initial acceleration. This hesitation is the time delay between the change in throttle angle (TPS) and the power output of the engine. Manufacturers can install a small turbocharged engine in their vehicles, providing extra power and still saving on engine weight and size.
