Fuel mileage versus injector issues

Has anyone experienced injector failure with a LB7 that was pulling 25mpg's on winter fuel? Seems to me that if the truck is running that well its a different problem.

It depends upon whether you are going by DIC MPG or had calculated. If going by DIC, it will show better MPG than actual since more fuel is going to the engine than the computer knows about. At least that is the way mine acted. DIC was showing about 15% less fuel used than actual. New injectors restored DIC to within 1 or 2 percent accuracy on fuel used.
