Post subject:  EVIC mileage after lift pump install...

Has anyone else experienced what seems like a drop-off in fuel economy (according to the EVIC) after installing a lift pump? My hand-calculated mileage seems fine, but the running total on the headliner console always seems to be about 3mpg off (farther than it already was). Could this be due to how/where it measures fuel usage? Perhaps it's calibrated for the gph of the suction pump and the increased flow of my cummins unit is throwing it off?

My evic mileage inaccuracy (10% optimistic) did not change with the Lift pump upgrade.
