Email Shaun at AED.I took off my catch can and engine cover. Nada. Found one of the motor mount bolts slightly loose and got excited thinking for sure I had found it. Tightened it up and still no difference. Banging around on the exhaust I do notice some resonance that sounds like it's coming from the mufflers. I've read that others have had problems with the MBRP mufflers coming part internally do I pulled the whole catback off and ran down the street on open headers with my off-road leads. Talk about loud. It only took me a mile to determine that was still no better so I went back home. I'm out of ideas.
We couldn’t diagnose the source of the false knock on my car then Shaun started seeing it on a few cars on the dyno when none of the usual suspect areas for knock were causing it. The knock sensors are super sensitive and upping torque seems to set them off on some cars. Shaun has turned the gain down very slightly on mine and it’s not knocked since.
