Some 2008-2010 Ford F-Super Duty 250-550 trucks equipped with a 6.4L diesel engine may exhibit a lack of power with an intermittent DTC P0088 at full operating temperature during moderate to heavy acceleration. A calibration update is available to resolve the concern.

If DTC P0088 is stored, reprogram the PCM to the latest calibration using IDS release 79.05 or higher.
