The Banks Power BigHead Wastegate Actuator addresses the issue of reduced midrange torque caused by the stock actuator opening prematurely under high boost pressure. By doubling the diaphragm area and spring tension, BigHead keeps the wastegate closed for a quicker boost rise and then precisely controls its opening to maintain peak boost. This results in crisper acceleration and improved mid-range power compared to using the stock actuator or bleed orifices (boost foolers).
