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.

Awesome
This big head turbo waste gate really woke my old truck up. Before I could only get about 8-10psi boost. Ow I’m getting 17-19psi boost at WOT.

Installation was a breeze since I already had my turbo off (for WW2 install). Preloaded the actuator to the suggested amount. Prior to doing the WW2 and BigHead upgrades, I had put in a Hydra and 4" exhaust. I would notice when I hit about 12lbs of boost, my stock wastegate would start to shudder. With this one, not even close. With the upgrades I've done (Hydra, WW2, BigHead, MBRP Turbo back 4" exhaust, FRX, HPX) I went from topping out at about 18lbs of boost to maxing out at approximately 25psi before my check engine light comes on and the MAF signals to defuel. About $2k worth of upgrades, but definitely worth it.
Riffraff always provides super quick shipping and awesome customer service! -

Impressive product... Definitely an upgrade! I will never go back to an OEM actuator! This thing holds your boost longer and I don't know how, but it seems to build faster too! I haven't been able to tell if I've blown it off the seat... Me likey!
