Maybe I haven't spent enough time looking at dyno graphs and trying to understand them, but can someone help me out here? I'm in a debate on another board, and I'm not wording my argument correctly. Let's say you've got your engine pretty well tuned (hypothetically). When looking at your dyno graph and trying to determine shift points, wouldn't you want to shift at the point where the slope of the tangent of the "horsepower" line goes from positive to negative? To try to maximize area under the curve? Or is it for a different reason? Can anyone help a brotha out? Thanks y0.
