Yeah I have great looking graphs from the chassis dyno sessions with my Coronet. That is a manual transmission so we just get it up to speed in 5th gear and then floor it. The curves come out looking just like engine dyno curves. However, I've been at the chassis dyno (same dyno) with automatic cars and the graphs are a mess. The combination of a torque converter and the kick down function turns the graphs to mush. I'll probably try it again with the Duster just for grins.
