Just got my first diesel, and yes I'm fully aware of the issues with the 6.0's Mine only has 98k on it but I know its a matter of when , not if the issues will happen. But, with that being said.. I have some questions. Being my first diesel, driving down the road, the boost is a almost 10 psi. Is that normal? Not ALL the time, but for the most part when at 70-80mph on the highway. It gets a solid 16 mpg.I literall just got it Friday and went on a highway trip to check the milage.Put a whole 275 miles on it since I have owned it.The reason I wanted it. Had 6.0 gas chevy hd 4x4 that got 8 mpg normal driving and stock everything. Another question... see how this sucker is skyjacking in the rear? Its like 6 inches higher in the rear!
