Your answer is in this article:

The electronic brake (and traction) control module (EBCM/EBTCM) controls a bi-directional magnetic rotary solenoid. The solenoid is located in the steering gear. The solenoid adjusts the amount of power steering assist in order to achieve a given level of driver effort in order to turn the vehicle. The EBCM/EBTCM varies the steering assist by adjusting the current flow through the solenoid. The amount of steering assist adjusted for steering is dependent upon vehicle speed.
As the vehicle speed increases, the following actions occur:
The steering assist decreases.
The driver effort increases.

As the vehicle speed decreases, the following actions occur:
The steering assist increases.
The driver effort decreases.

Thank you for the great answers. I was just clearing up some misconceptions some had about it.

i thought it was the faster you drive the stiff the steering gets so you cant just jerk the the wheel and lose control.

Yup that whats happening Steve, as the speed increases the magnasteer decreases.
Meaning you have to work harder to steer.
