Maybe the problem is with the Dynojet's compensation for the torque factors of different gears? Or maybe the Dynojet isn't taking the different between the 6MT and 7AT into account when computing torque? It seems it should get the same answer in every gear if it was doing the math/model correctly. BTW, I attached the PDF of the iPad spreadsheet I use to compute speed/torque in gears. It is based on hand interpolating from a large dyno scan and uses the same values for auto and manual (which should be right, I think) but some day I will update with some more precise figures. It was originally done to show why you should shift at redline.
