Datalogging looks the same as the first run?. Car runs clean the rest of the day.

Do you fog the engine after every race day? Next time you head to the track, do your warm up and pull the carb to check intake plenum, I bet some of the oil is present until you make a complete pass washes it out.

No Carbs. I can look into the combustion chamber. Just by opening the throttle plates. Haven't fogged it. Leaks down 3% or better.
Going to try a new set of plugs old ones have about 75 runs on them. And I don't have a MSD to keep them clean.
