Yeah, I've done a lot of small sound-deadening and isolation stuff around the car. For the most part, it's pretty streamlined now.Sort of related also but the vibrations I have been having are almost resolved. It took a lot of sound deadening and taking shit apart but I’ve isolated most of them.
One thing I will add**** when I first started toying with the RMM’s, I noticed that the NVH was worst at idle.
I simply went into Ktuner and set my idle 250 rpm higher. Took the vibration out.
Also, I had the most vibration issues right at 2,000 rpm. Just seemed to be the vibration frequency point.
