Thank you for the replies. they are all coming in late except lockup. I launch in manual first and when I get straightened out I slap the stick to drive. My tach dances and I don't have a speedo so im going by video and time slips. Im hitting overdrive at the 1/8 im running about 107 and I want od at 81.

heres my anteater schedule
1-2 30 mph
2-3 58 mph
3-4 81 mph
lockup 14 mph
gov psi modifier @ 45
I launch at 2700 and im sure it rips past 4k before it can lock the converter. then I feel it lock and I smack the stick to drive, it hits second but its around 4k then 3rd around the same, I have to wait for overdrive and I get that at the 1/8 around 107.

here is mph vs rpm from a gear calculator

1-2 locked 30 mph = 3000rpm drop to 1700 in second
2-3 58 mph 3400rpm drop to 2300 in third
3-4 81 mph 3200rpm drop to 2200 in fourth

what has me thinking is that 107 mph in third is around 4300rpm how much lower should I adjust? Its off by almost 1100 rpm..I understand if it overshoots each shift it may take a second to figure out where it needs to be and that's causing the delay... Would it be easier to change the shift springs?
One other thing is im around 90% tv it will hang the shift from 2-3 and lay right over on the governor, im set at about 75% now..Here's 2 passes you can hear it wound up and see the smoke fade on the shifts 5000 gsk.
