do you have a scanner? a stock pcm? If so when you get a chance could you check out what your 2-3 shift is at? My 1-2 does seem to be higher then my 2-3 shift.

This is true.
I did find however that the dash tach can be as much as 200 rpm off from a scantool.

And yep the 9 vane 4t60 pump wasn't enough to keep up with my 6400 rpm shifts. The 65 has 11 vanes FWIW.

no i dont have a scan tool yet, but i am going to get one before i get a new pcm. That is what i was thinking about stock points about 5700-5800. I know for a fact now.... raising my shift points up to 5900 will help me a lot in the 1/4, because i shift right at the end of the 1/4. With 5900 shifts i will be able to make more power longer before i shift back down to 4000 rpms :(
