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.

A BIG Plus over stock
This was a very nice improvement from stock. Creates more boost and holds it longer for better towing.

Bighead wastegate
My old wastegate actuator "failed steady state", needed a new one and have used Riffraff for other products and like their service. New waste gate actuator works great and no black smoke when getting on it.

You gotta get this!!!
I replaced my stock waste gate actuator while doing an EBPV delete. Let me tell you, I noticed an immediate and recognizable difference in throttle response and boost with the Banks Big Head. I recommend it to anyone with a tuner, intake/exhaust mods. I also noticed a drop in RPMs while cruising on the freeway.

Great performance addition worth the time to install
Installed this actuator on my wife's 2002 Excursion 7.3. Took about 3 hours to do, as I had to remove the passenger side intercooler pipe to get room to work. Unbelievably strong acceleration now that the wastegate is no longer being pushed open. RiffRaff had the best price I found on it also. Great product!

great upgrade
Added to my stick turbo 02 7.3 and loved it the first time I test drove. Went from 24-25 psi of boost to 33 lbs of boost. Very happy
