Right now my cruise rpm is about 1800 rpm most of the time (when I'm on the highway). This works out to be 60 mph. Idealy I'd like to slow down a little bit more but here in Indiana the interstate speed limit is 70 mph, which means most people are going around 75 mph (65mph for semi trucks). I feel like going anything less than 60 mph almost becomes a hazard.

As far as the powertrain modifications go, I'm not sure how you all roll on this site. I'm all for sharing tips, but you see, some of the modifications I have made may or may not be considered legal by the EPA .
