I'm getting some knock from 2nd to 3rd that seems to be real. The RPM's are a bit erratic dipping and rising before they finally settle back to rising at WOT, however the knock doesn't go away. I have eliminated fuel as the issue as fp rises with boost and injecters have been replaced with know good ones. I am thinking its ignition but of course all the tune crap has been done many times over with the know products that work. Not sure what to make of it, but i'm wondering what the symptoms are of a coil going to sh** or IM? I have also closed the plug gap with no success.
looking for some ideas or basically signs of a toasted coil or IM.
edit: also raising FP changes conditions in the cylinder enough to lower the knock but not that much. Even 60psi test don't do the trick. Just a FYI
TIA
