I think i would have to make the comparison when i have the Jeep on the dyno. Doesn't sound possible to me. As i remember the pulls in 3rd were relatively the same in 3rd vs 4th. Certainly nothing that I recall that would make me choose one over the other. I think 3rd may be a better choice to see the dip in power that is in question.
