You missed my point though about the DYNO, it doesnt matter if you have 350kw or 355kw at peak rpm on a dyno (which is only a tuning tool), its the initial acceleration, from standstill, a efficient motor with less power will initially outperform a less efficiant one with more power, and when we are talking about a only a few kw its not enough to makeup for the weaker performace down low.
Im sure a dyno can be set up so that you can get on it from idle and go through the gears to access the acceleration charicteristics, Im far from a expert on this.
Sorry if Im confusing things, I know what Im meaning to say, COLD AIR GOOD, HOT AIR BAD, LOL.
