What, if anything, did you change from last fall?

The hesitation is from a lean condition, and it happens 20 to 25 ft out. So, it could be the squirter duration may needs to be lengthened. Or it could be that the vacuum secondaries are starting in a bit too early. If tuning the squirter does not help, try a slightly stiffer secondary vacuum spring. These are all simple things that you should do at the track to get it right.

I think it is always a good idea to understand changes in the mph. The atmospheric conditions from last fall to this spring could be the answer. If that is the reason, simply waiting for the same weather conditions as last fall alone will put you into the 12s. Your 60 ft this spring must be a little better than it was last fall as the ets are about the same but with 2 less mph.

To really fine tune for performance, you need to acquire a weather station so that you can truely compare run to run changes. You can buy an inexpensive weather station and collect the temp, pressure, humidity (or water vapor pressure), and get the formula on line to determine the DA for each run. It won't be real time for tuning at the track, but you can compare the results when you get home.

Make sure that you find the very best shift point rpm for each gear. My cars have been pretty sensitive in both et and mph on shift point. Most important, where ever you choose to shift, be consistant.
