My truck is an 05 and it has been having two issues.
1. The turbo sounds like its winding up and down going down the road at a constant speed. Not a normal turbo spool. Really quickly. Thought it was egr valve . Unplugged it. Same thing. So I have turbo out and being cleaned.
2. While I have the turbo out I would like to fix my idle problem. I think it's high pressure oil related. It is not really an outstanding noise but I can defintely hear the motor going up then down when idling. I had another 6.0 that did this. Turned out to be stc fitting. Tore into this truck to do fitting upgrade and it already has the big brace that holds the branch tube. That is the upgraded version right? The support that bolts down across the back of the pump?... What else could the sporadic idle be then? Icp? Ipr? Stand tubes? Pressure on my scanguage for icp is about 590 give or take 15 to 20 when warm... Any help is greatly appreciated. Thank you
