There should be only so much you can get out of a T from stock components, no matter how much it has ben run in. Your, injectors are probably still gonna be the limit and should only be able to push so much. If you have a freak stock car, doesn't mean it will be able to pull and extra 30 or so rwkw. Lets not forget that this is only a peak figure and there is much more to a car than its peak figure, there are plenty more revs than that! As for AFRs that does seem pretty lean for stock, but anyway, good to see some good figures, but dont get to carried away with dyno numbers.
