Turbo Charger: Controls
Turbocharger performance has improved with the use of computer controls. The computer module is monitoring boost pressure, throttle angle, air flow and more.
Early model turbochargers suffered from 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. Manufacturer's can install a small turbocharged engine in their vehicles providing extra power and still saving on engine weight and size.
