GenV CompGate40 CG for Compressed Gas and C02 External Wastegate is designed for control strategies that require a large tuning window and large pressure differentials from the top to lower actuator housings, whereas traditional actuators on poppet style gas can achieve around 2-3x base spring pressure, the CG / C02 Version is capable of extreme multiples of the base pressure through the use of additional reference signal, high-pressure gas and C02.
