1St gear before shifting lets you go into the 6000 range comfortably, and doesn't shift till almost 42/43 mph . 2nd has been going to 65....havrnt really paid attention in 3rd and up but the car pulls so much better. I think the spacing has significantly cooled down the ambient temp if the manifold. Now excuse me if I'm wrong, but from stock to this it is definitely a gain. I will say that driving it heavily the past weekend in the hot GA heat has really helped me form an opinion. I'm averaging 22mpg city up from my 20ish, with my foot down all the time, and still no issues. ...
OK.... I guess the hypothesis would be the ECU senses the slightly lower temperature and allows higher shift points (not really redline, but close enough for this conversation) for the AT. Conceivable, I guess.
