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.

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

I looks like according to the scantool the top of second is 5750 @ 88 Mph
God My gages are way off..
700-725 at idle..
I didn't get a good read on the First to second shift... But I think it shifted at 46-47 at 5800-5850 Rpms...
And OMG 1350 Rpms at 46 mph
TJ do you have a scan tool to scan with too see what you points are? You really wnat to know before you make changes..
BTW, Don't beat me... But my PCM had been dissconnected... Its learning again

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 :(
