Nope.
On a heavy duty actuator, typically 1 half turn of the turn buckle rod equals 1psi of boost. And on a standard spring actuator, typically 2 half turns (or 1 full turn) equals 1psi of boost. Now, this can vary from car to car and turbo to turbo, but this should be very close to accurate. The difference between the two are the spring rates. Obviously, the HD actuator has a stronger spring than the standard spring actuator does.
