X15 2450 low power high fuel consumption

Wow, that is interesting information. This leads me to believe the issue probably isn't the calibration. As I was running across Montana today I plugged in to the truck I'm using just to try to compare the two watching data. This is a x15 2350 in 565 1850 torque so maybe like comparing apples to oranges. Anyway I notice egr commanded and measured maxed at 45% open, mostly hanging around at 20 to 30% range. So now I'm wondering what conditions call for the egr valve to open more. Like I mentioned, mine seems be hanging out at 70 to 80%. Also I noticed the throttle valve doesn't close on this one going down the road.
