Do you know one of the most failure prone parts on a 7.3L Powerstroke? The EBV butterfly valve on the backside of the turbo. And do you also know the most common upgrade on these trucks? You guessed it, a non-EBV pedestal and outflow valve. Unfortunately, when you change these parts out, you'll typically also get a check engine light or soft code P0475. If you don't like lights on your dash, this inexpensive and easy to install pigtail from Full Force Diesel will help get the job done.
