I am definately going to get a TW asap.. But I am thinking that I have a fuel delivery problem or something. While I had the turbo apart doing the WW, I checked free play and everything spins freely, so I don't think the turbo is hurt.
But I cannot build over 20 lbs of boost even when pulling 8000lbs uphill with the pedal to the floor. Also, the EGT's never pass 1000. I have a slight surge at low speed and it will use 2 or 3 courts of oil every other tank of fuel. I haven't noticed any blue smoke out the exhaust, and the coolant isn't showing any signs of oil. I park the truck in the same place every night and no puddles, so I have no idea where all the oil is going.
The valley is always slightly damp, but no standing puddles. I changed the fuel filter and run additive in every tank of fuel, so fuel condition shouldn't be a problem. I am just wondering if maybe I have an HPOP dying or something? Not even sure how to diagnose that one?
At this point I am thinking about buying the Auto Enginuity program cause I am under the impression that you can check all kinds of engine performance perameters with it.
I don't know where to start, so I am hoping one of the 7.3 gurues will chime in.
Thanks in advance for any help.
