Open up your scan tool and connect to the trucks ECM. Truck is better to be running. Open PIDS tab and highlight all 8 injector balance rate until the speedometer looks like it is colored. Then hit the little red or yellow button at the bottum of the screen and watch it in the DATA tab.

Balance rates are +/- 4 running in "N" and idle, and +/- 6 in "D" at idle. Anything up to +4 or -4 is ok in "N" and I think you get the point.

Hope this helps,
Tony
