2) The HP/Torque crossover moves up about 2,000 RPM between the before and after. I know when using the standard US units (Horsepower and Ft/lbs) the crossover should always be at 5252 RPM, which the "before" graph appears to be at...), but perhaps whatever units they are using make that work out differently. Or perhaps there's some error in generating the graph, I don't know.
