I have instaled the edge mod and 4' pipe a few months ago.Just resently I have found that the engein is makeing more noies,almost like a lifter noise or clacking if that makes sence.Is very prominant at idel or low RPM.I Know this is a diesel but thier is a differents now. Has this happend to enybody or if you have eny ideas I would appreseat it.

unplug the edge and see what happens.

given the time of year my guess is poor quality fuel. Like stated un plug your juice , it will change the tone of the motor slightly. I would also add a heathy dose of fuel system cleaner / cetain boost.
