    Injector knock

    Hi everyone. I have 2013 Ram 3500 - 6.7 Cummins. It’s been deleted. Running a bully dog tuner, fass titanium 150.
    I have a injector knock on acceleration.
    I’m thinking it could be the FCA. I recently added the FASS fuel pump and thinking maybe some debris got into the fuel line, when I routed the fuel line up to the CP3.
    Would appreciate any thoughts
    Thanks

    I would load stock file back in and see if still there before digging deep. Some of these file have agesive knock to them. Yes you will see all kinds of codes pop with stock file we're doing for diagnosis.
    The injector knock will be more noticeable in cold weather. Good luck

    FYI The injector tubes have sintered bronze filters in them. They are good for stopping larger debri. If I recall, they are good for 50 Micron which is pretty big. If you got junk in the injectors, they would just quit. As said, remove the program and see what happens.
