How much improvement will I see?

I have about 30 passes on this combo in 4 different outings. MPH was as low as 102 and as high as 104.5. My bestpass is the time slip pictured at the bottom of my original post.
I was having trouble getting it sorted out, it would either sputter or spin. I kept increasing my squirter size to get rid of the off idle sputter, but it was when I finally started going down to smaller squirters that the stumble started improving. I ran out of season before getting it sorted out.
My timing was 25 initial, 35 total, all in by 2500 or less. I did try timing locked out at 35 but noticed no difference.
Aa far as traction, I have 275-60-15 Nitto NT555R Drag Radials. I experimented with pressure and tried as low as 15 psi. Finally, I found 24psi where I got my best traction. Totally not what I was expecting. I will get better drag radials, likely Hoosiers. I won't go to slicks, at least not now. I drive the car to the track.
