Has anyone encountered a weird vibration from around 3k RPM to about 3400 RPM? I do have the Cobb RMM, but this rattle began months after install so I don't think it's the case. I know car is getting older and it's almost at 20k miles and inherently rattles will occur. In my case it almost seems like the dash is vibrating against the glass. It's become annoying and I want it gone! lol
Any assistance in removing this rattle from my life is much appreciated.
