Well, I haven't seen times, but I can tell you that if your in regular shift mode, when it shifts from 1st to 2nd, the rpm's fall so far back, your way out of your powerband. You won't run a good time at all. Truck loses everything right there. I would recommend manually shifting it, and definatley do not shift it off the rev limiter. Hit the button. Like as soon as it comes past 5k or so. It will end up shifting at 5500 or so. You might need to play with that receipe
