How does the Big Head Actuator improve mid-range torque?

The stock actuator's spring is too weak and allows the wastegate to open too early, limiting boost. The Big Head Actuator has twice the spring pressure and diaphragm area, keeping the wastegate closed longer. This builds boost faster and holds it longer in the mid-range, producing more pulling power.

What is the main difference between this and a 'boost fooler'?

Boost foolers only trick the computer and don't address the mechanical issue of the wastegate opening too soon. The Banks Big Head Actuator physically holds the wastegate closed longer and controls its opening more precisely, directly solving the problem of lost mid-range boost.

Is this actuator CARB approved?

No, this part is not CARB approved and cannot be shipped to California due to emissions regulations.
