It's looks to me that the difference between the two graphs could almost be the difference of two simultaneous runs with no changes to the car. Meaning that if a guy does one pull on the dyno, changes nothing, then does another pull then the graph could look very similar. It's appears as if the drag put on the system by the AWD doesn't affect the numbers regardless of if the AWD system is "deactivated". Despite the dyno numbers not being spectacular, shouldn't we see an increase in WHP if the AWD system was truly disengaged? I see that the front are not turning so does that mean that there is some slipping of a clutch or whatever is going on in the tranfser case?
