soft loc or advanced launch question

I'm still sorting mine out, it's one of Robs clutchs.
appox 3380# , leave @ 6K, 1100# base pressure, I'm running the counter weight he shipped it with.
Total 1st gear is 11.38, 28.5" tire.
I used my EFI data loger one time. That pass it pulled down to 4950rpm, that was with old tires, 1.47 60'.
Made one pass with new tires last week. I added 1/4 turn base pressure, thinking more bite would need a little more clutch, It worked, went 1.38 60', but the data loger failed.

Here's the video maybe you can hear how much it's pulling down? about 1000rpm? 6K on the two step.
