99.9% dyno machines are calibrated for 3rd gear.
Next time u guys go for dyno, I suggest a more advanced dyno machine and find out on wheel power as well as air/fuel ratio on the graph. From what I've seen at the dyno session, the machine used was quite primitive and only a few points of data was taken. Thats why you see the graph printed out is so smooth from point to point. The data in between points are not shown.
