If the ECM is commanding 26k then a new harness/ pigtail won't fix anything. Look at your multiplier tables in the tune (if you can see them, I'm not familiar with the UDC). If the rail pressure isn't overly high while cruising I wouldn't worry about it, more pressure = more power. 26k won't hurt a common rail.
