If it is hooking I believe the issue is lack of starting line ratio. My car has the same issue, only with a quicker car. I run a 4.10 as well. The cars I race in N/SS that run 9.50/9.75 tend to 60 ft in the 1.25-1.30 range. My car is in the mid 1.30s on most days yet runs .30-.60 quicker ET. They all run 4.30-4.56
