6.0 Alliant FICM

The 6.0L Powerstroke relies heavily on consistent voltage out of the fuel injection control module to properly fire the injectors.  The original FICM frequently fails and/or delivers less than adequate voltage, causing hard starts, rough idle, poor fuel economy, and overall less than satisfactory performance.  If your FICM is in need of replacement, check out this quality remanufactured unit from Alliant.
