Question about progressive controllers...

I realize that I should probably pull timing out to manage traction after the hit, but this is just a simple street car with a small plate kit. I am running radials, and track prep is not the greatest, when I have it come on right away, it would spin for 30 ft or so. I have a NOS mini progressive on the car, would it be worth it to try to delay, or progress the hit? The track is normally packed, I'm lucky to get 2-3 passes in, so I'd like to get an idea of where I should start, then I can dial it in from there.

I should probably upgrade the rancho shocks on the back, but I'd like to work with what I have for now. I think I might also go back to slicks just because of the quality of track prep here...
