A turbocharged engine produces more power overall than the same engine without the charging. This can significantly improve the power-to-weight ratio for the engine (see how horsepower works for details). in order to achieve this boost, the turbocharger uses the exhaust flow from the engine to spin a turbine, which in turn spins an air pump.

This technology turns off some of the engine's cylinders when they are not needed. It essentially turns off the valves to some cylinders so that fuel and air aren't pumped into them. This temporarily turns an 8- or 6-cylinder engine into a 4- or 3-cylinder engine, saving fuel.
When you’ve got a truck, you want to get as much horsepower and torque out of the engine as possible so you can get work done. Some trucks do this with displacement – by putting the bigges.

A turbocharger is a turbine-driven forced induction device that increases an internal combustion engine's efficiency and power output by forcing extra air into the combustion chamber.
Forced induction technology (turbocharging and supercharging) can enhance the performance of an internal combustion engine by compressing inlet air charge.
Although today's turbocharged four-cylinder engines do offer more absolute power than naturally aspirated v6s, the situation is usually different when you analyze powerplants in the same car lineup. In the rare occasions when a given vehicle offers both types of engines, the v6 tends to lead the way, at least for horsepower.

Each turbo is designed to support a specific range of horsepower and engine displacement. To help you select a turbocharger that meets your horsepower and engine requirements.
Turbocharged engines use a device that forces in more air than a normal engine would receive. More air — and more fuel — makes an engine more powerful. The device that forces this air into an engine is a turbocharger — and some use the word “boost” to describe the process of turbocharging.
Even if turbocharging was adding significant boost to the output power, the high fuel consumption of the (gasoline) engines and the turbo-lag behavior (delay in engine acceleration) were seen as a drawbacks (compared to naturally aspirated engines) and stopped vehicles manufacturers to use turbochargers on a wider scale.
Indispensable for engines that must offer high power densities, as well as for low-emission diesel engines. Moreover, turbocharging is seen as a means of reducing fuel consumption by enabling downsizing and lean-boost for direct-injection gasoline engines.
