Bleed orifices (also known as \"boost foolers\") just make it worse. Only Banks solves this problem by replacing the boost actuator. BigHead holds the wastegate closed for quicker boost, then controls the opening to maintain peak boost for superior acceleration and mid-range pulling power. BigHead Wastegate Actuator Kit for use with 2001-2004 Chevy 6.6L. Power Now! When turbo exhaust backpressure increases, the stock actuator prematurely blows off the seat, softening boost in the midrange and killing torque. With twice the diaphragm area and spring pressure of the stock wastegate, Banks BigHead Wastegate Actuator keeps the valve seated longer and achieves a higher peak boost, sooner. At peak, BigHead opens the wastegate and holds its position, for precise boost control that gives you crisp acceleration and more mid-range pulling power. Key Features: Quick, Controlled Boost. Produces massive torque right from idle. Doubles stock's diaphragm area and spring pressure. Keeps the valve seated longer achieving higher peak boost, sooner. Crisp acceleration and more mid-range pulling power.\u003c\/p\u003e\u003cbr\u003e\nFits\u003cbr\u003e\nChevrolet Silverado 2500 HD Base 2001\u003cbr\u003e\nChevrolet Silverado 2500 HD Base 2002\u003cbr\u003e\nChevrolet Silverado 2500 HD Base 2003\u003cbr\u003e\nChevrolet Silverado 2500 HD Base 2004\u003cbr\u003e\nChevrolet Silverado 2500 HD LS 2001\u003cbr\u003e\nChevrolet Silverado 2500 HD LS 2002\u003cbr\u003e\nChevrolet Silverado 2500 HD LS 2003\u003cbr\u003e\nChevrolet Silverado 2500 HD LS 2004\u003cbr\u003e\nChevrolet Silverado 2500 HD LT 2001\u003cbr\u003e\nChevrolet Silverado 2500 HD LT 2002\u003cbr\u003e\nChevrolet Silverado 2500 HD LT 2003\u003cbr\u003e\nChevrolet Silverado 2500 HD LT 2004\u003cbr\u003e\nChevrolet Silverado 2500 HD WT 2004\u003cbr\u003e\nChevrolet Silverado 3500 Base 2001\u003cbr\u003e\nChevrolet Silverado 3500 Base 2002\u003cbr\u003e\nChevrolet Silverado 3500 Base 2003\u003cbr\u003e\nChevrolet Silverado 3500 Base 2004\u003cbr\u003e\nChevrolet Silverado 3500 LS 2001\u003cbr\u003e\nChevrolet Silverado 3500 LS 2002\u003cbr\u003e\nChevrolet Silverado 3500 LS 2003\u003cbr\u003e\nChevrolet Silverado 3500 LS 2004\u003cbr\u003e\nChevrolet Silverado 3500 LT 2001\u003cbr\u003e\nChevrolet Silverado 3500 LT 2002\u003cbr\u003e\nChevrolet Silverado 3500 LT 2003\u003cbr\u003e\nChevrolet Silverado 3500 LT 2004\u003cbr\u003e\nChevrolet Silverado 3500 WT 2004\u003cbr\u003e\nGMC Sierra 2500 HD Base 2002\u003cbr\u003e\nGMC Sierra 2500 HD Base 2003\u003cbr\u003e\nGMC Sierra 2500 HD Base 2004\u003cbr\u003e\nGMC Sierra 2500 HD SL 2001\u003cbr\u003e\nGMC Sierra 2500 HD SL 2002\u003cbr\u003e\nGMC Sierra 2500 HD SLE 2001\u003cbr\u003e\nGMC Sierra 2500 HD SLE 2002\u003cbr\u003e\nGMC Sierra 2500 HD SLE 2003\u003cbr\u003e\nGMC Sierra 2500 HD SLE 2004\u003cbr\u003e\nGMC Sierra 2500 HD SLT 2001\u003cbr\u003e\nGMC Sierra 2500 HD SLT 2002\u003cbr\u003e\nGMC Sierra 2500 HD SLT 2003\u003cbr\u003e\nGMC Sierra 2500 HD SLT 2004\u003cbr\u003e\nGMC Sierra 2500 HD WT 2003\u003cbr\u003e\nGMC Sierra 2500 HD WT 2004\u003cbr\u003e\nGMC Sierra 3500 Base 2002\u003cbr\u003e\nGMC Sierra 3500 Base 2003\u003cbr\u003e\nGMC Sierra 3500 Base 2004\u003cbr\u003e\nGMC Sierra 3500 SL 2001\u003cbr\u003e\nGMC Sierra 3500 SL 2002\u003cbr\u003e\nGMC Sierra 3500 SLE 2001\u003cbr\u003e\nGMC Sierra 3500 SLE 2002\u003cbr\u003e\nGMC Sierra 3500 SLE 2003\u003cbr\u003e\nGMC Sierra 3500 SLE 2004\u003cbr\u003e\nGMC Sierra 3500 SLT 2001\u003cbr\u003e\nGMC Sierra 3500 SLT 2002\u003cbr\u003e\nGMC Sierra 3500 SLT 2003\u003cbr\u003e\nGMC Sierra 3500 SLT 2004\u003cbr\u003e\nGMC Sierra 3500 WT 2004","brand":"Banks Power","offers":[{"title":"Default Title","offer_id":54506307518769,"sku":"4379435","price":235.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0990\/2247\/1473\/files\/92a850b067bfc3ad3117a74e599681c8.jpg?v=1781183425","url":"https:\/\/shop.topspeedcincy.com\/products\/banks-power-01-04-chevy-6-6l-big-head-wastegate-actuator-kit-for-gmc-sierra-3500","provider":"Top Speed Cincy Shop","version":"1.0","type":"link"}
