What you could have ascertained from this is that it may tell you that your air-filter is dirty,maybe a blockage in the induction (birds nest , bee's nest, or that you need to downshift to increase cooling air through your air-charger (inter-cooler) ... You may note that diesel engines react different than gasoline engines ..say in an aircraft...
If everything is working perfect the DD will take care of you without one... but it is another way to monitor your engine..if it isn't
Most all trucks have them ..but they are working them a lot harder and shifting gears manually..
