I was curious about this topic as well. For me, on local streets, I try to keep the RPM between 3k and 4k because of the IMSB. On the freeway, I'm usually in 5th gear cruising at 60-75 mph, which results in 2500 to 3000 RPM. I feel 3000-ish is a good balance between fuel efficiency, torque, etc., but I'm really annoyed by the vibration at 3200 RPM.
