Here are 2 data logs from various times this year. The first was on the dyno with fans blowing air right into the intercooler, and the second is of a pass in 85 degree heat.

Looking at the 2 IAT graphs, would you say that my intercooler isn't working enough, or that I'm not getting airflow to my intercooler when on the track? It's hard to tell due to the short dyno pull whether or not the IATs would continue to climb, but the IATs at the track are getting to where the car is slower on more boost because of the heat. I have a CX Racing intercooler with a 3" core and run on 93/110 mix at the track. I'd like to avoid buying a meth kit if at all possible, but the Florida heat might say otherwise.

I've also attached a piicture of intercooler placement. We've made back-to-back passes with bumper on and off and no IAT changes were noticed.

I'd say the IAT'a are too high. Can you make a dummy pipe to replace the IC (so no intercooler) and log IAT's?

Also, your injector duty cycle would worry me.

Meth injection would fix the some of the IAT and injector duty cycle issues.

We've addressed the injector duty cylce issue on the first log - we had a clogged fuel filter. The dummy pipe is a good idea, I'd also like to data log temp before the intercooler as well as right after.

That intercooler is junk. My chinabay 24x12x3 core would rise 80 degrees in a pass on only 15 psi. I had a custom a2a built using a quality Garrett core but my car isn't back together to see the results yet. I'm expecting only a 20-30 degree rise on over 20 psi though. To answer your other question, a few second dyno pull isn't going to raise IAT much at all.

Your IATs are less on your dyno pull because you were running less boost and it looks like you barely got into it.

Second graph looks like a much longer pull, so your IATs were going to rise a lot further.
