I remember one change (I think it was 2-3) hanging a bit more than I liked when I had a stock valve body, but if it is shifting cleanly from gear to gear with no more slipping, it sounds like you have most of your issue sorted. I have my kickdown cable fairly taught, with upshifts taking place somewhere around 3700 at full throttle, but that comes down to what feels right to you. As long as your exhaust is in decent shape, you should feel the power starting to build at 2500 and really come on tap at 3000 and above. That's why I like the higher shifting.
