I have a 3116 Cat engine in a 92 GMC Top Kick Toterhome. It runs great and does fine on flat ground but when you get to a hill it has no power at all....when you really mash on it to maintain speed it just bogs and puts out a little white and blue smoke...i have also noticed that even in a bind i never hear the turbo and thought that was odd...i have already replaced fuel filters..any ideas?..thx Justin

How many miles on on it?  need to hook up boost and fuel pressure guages to the truck and monitor them.  That will give you a base line on what you have going on with it and where to start looking at.
