Anyone have info on the EVO actuator?

[NYC LS8]

I believe the EVO (Electronic Variable Orifice) feature on my car is screwed up. While on the highway, the steering is VERY touchy and makes even changing lanes an adventure (nevermind the sweeping turns on interstates).

Anyone here know where the actuator is located? On the power steering pump possibly?

TIA :Bang

Nobody, eh?

I've since found some since I got home from work, on my All Data CD
