Last but not least I gave the automatic tranny a big benefit of the doubt with enagage time and shift time of exactly .1 seconds (fast). Still the numbers are nowhere close to quoted figures. I think they are significantly under rating! Either way if they do get the straight line numbers the mag. reported it will be a really fast car. I have to try a few more custom transmission parameters as it looks like the sihifts are not quite fast enough in the acceleration graphs but for now
I fully call under rated.
