Generally these calculators use measured data from thousands of data points and then apply a curve fit. As I said, I don't believe in dyno results either, or at least not rolling dynos.

BTW, having a sufficient number of gears is good, but you are applying zero power while shifting, so having more gears isn't always better.

2013 X5M ........ 2013 650xi ...... 2011 550xi (ret) 2011 335d (ret)
