looking at yours thast a good strong graph there, would be interested to see what caused he hiccup in the middle, it seems your torque holds up better than mine later in the RPM band as well. wander if the performance panel filter helps that, a little, i might get one as a little stop gap before i et another intake.
^^Why did they do the RR in 5th gear? 
they use this gear as it is ' the closest 1:1 gear ratio. (although others use 4th and say the same). Like hedge though, im not sure if it would have a bearing. It should make roughly the same power, in 4th or 5th id guess, just with a longer period to run upto the redline, so you'll get a higher sample rate for the graph
