I don't think so? I tthink nos is sent to the engine in the air intake. Normal turbochargers work by using the exhaust to sort of act as an air compressor and pump more air coming into the engine. Because of this turbochargers work better at higher speeds (becuase more exhaust powering the system). I think this is just kickstarting the process to engage the turbochargers earlier at lower speeds to get an edge on others. But I'm not a car guy, so I'm not actually sure.
