Been running them for a while now and i love the tunes, but honestly i don't think the valvebody is... that great. You only notice a difference shifting to 3rd sometimes, and if you manually shift it into overdrive. Tranny now has a little leak, i think it overflowed some fluid first, and now it just drips very little because 2 of my pan bolts were stripped and won't get fully tight:doh:
