im going to the dragstrip on friday and plan on doing some tuning, when i am changing pump cams, where should i look for the difference to be? In the 60ft times, 1/8 mile times, where at? I played a little with pump cams earlier in the year and tried the blue cam on the #2 hole but it seemed like it was getting to much fuel to soon. So far it seems to run the best on the pink cam. Need help!! My combo is in my sig.

 

60'.

Assuming traction doesn't vary.
