Holley/Demon Carb stumble

As far as the starting line experimenting.
I have learned that 2200 stall take all the stretch out of the suspension with this new converter and causes traction problem when the bite goes away.
I have a light on my dash, that comes on when i'm at my starting line stall rpm. It has been turned down to 1600 rpm and seam to work well. It launches just as well at a idle(when its not bogging) but my Reaction time REALLY goes in the toilet!
To be honest, i have never tried to roll the throttle to the floor, will have to give that a try.

Traction is at the bottom of my list at this point. But was at the top of my list,after i installed my new converter last year.
When its bogging it don't seam to give two ***** what i stall it at. It just fall on its face.
