    I read some threads pertaining to the EVO system used on gm truck power steering from 97 on. I couldn't find if anyone has ever removed it. I put a new pump on my 97 1500 and it appears removing the needle from the valve would provide full assist at all times. The truck only gets 5-7k annually and most is with the plow on otherwise I wouldn't consider it. I ve had assist problems in the past and would like one less thing to fail during an event. The system was flushed at pump replacement.
