I'm still struggling to do everything possible to eliminate that vibrations.
As talking about Power Commander 6, as I understand this box isn't a simple plug & play device, it needs to be tuned/calibrated by a specialist so, another costs(not small)? Thank you for your answers!
If your complaint is vibration, specifically high-frequency vibration, that is the nature of inline 4 cylinder engines - they all buzz. If you search the archives for vibration, you may find plenty of threads on the subject.
High-frequency vibration affects some people (like me) more than others. For some, it isn't even noticeable. Even with the counterbalancer, it can't be rid of. There is a premise that the designers introduced some lumpiness in the idle for "character", by mis-timing one set of intake cam lobes, but that may or may not affect the vibration.
