My first Thermoquad tuning question!

Took my NHRA Aspen wagon out Saturday with a test engine to make sure all the suspension mods worked and it went straight. Car ran well for what it is (7.57-7.61 @ around 88mph in the 1/8 w/1.57-1.58 60'.) But on the burnout, I started in first and before I got it wound up in 2nd, it fell on its face and stayed around 3k - 3.5k even with my foot on the floor. The subsequent run was fine. Would like to know what to work on next time out.

* Would the secondary adjustment be too light?

* What are the smallest tuning increments that would show a performance difference in a run? (1/8 turn, 1/4 turn, etc.)
