Got back out today, two time trials and 3 rounds of eliminations. New best, but 60's are basically the same.
Dropping the exhaust and adding the extensions saved 50 lbs, so new race weight is 3,530. On run two I dropped the cold air pressure to 12 lbs (was 13 after the run) and set the shocks at 6 clicks, which is basically the middle of the adjustments.

- 60 --- 330 --- 1/8 --- MPH --- 1000 --- 1/4 ---- MPH
1.486 - 4.160 - 6.453 - 107.50 - 8.429 - 10.111 - 133.49
1.452 - 4.099 - 6.372 - 108.10 - 8.336 - 10.006 - 134.30
1.444 - 4.113 - 6.394 - 108.06 - 8.358 - 10.115 - 124.94
1.458 - 4.118 - 6.396 - 107.81 - 8.361 - 10.030 - 134.10
1.469 - 4.131 - 6.414 - 107.48 - 8.384 - 10.056 - 133.96

Did finally notice that on the best run, when I "accidently" forgot to make the 1/2 when the light came on at 6500, and shifted at 7000, it semmed to like it, so maybe the extensions helped there. But, I made the 2/3 shift at 6700 and the needle on the tach didn't drop at all.

I'm pretty sure I need to have some converter work done and then I'll have to hold this thing back.
