The factory fuel injection control module or FICM in your 2003-2004 Powerstroke oversees of supplying consistent voltage to your injectors for firing. When your FICM fails, it will not deliver the proper amount of voltage to the injectors causing hard starts, rough idle, poor fuel economy, and overall less than satisfactory performance. The Synapse Auto Remanufactured Tuned 48v FICM is the perfect replacement for your Powerstroke.
This FICM is designed to supply your injectors the correct voltage to ensure your injectors fire properly. The Synapse FICM is available with either a stock, economy, 40hp, 80hp, or the Hercules 100hp+ tuning options depending on your application. The economy or added horsepower options are tuned by PHP and will offer the same reliability as a stock tuned FICM.
