On a relatively stock motor, I bet running with the intake an extra 20F-30F hotter means nothing. But on a motor tuned up to the limit might see detonation with that much heatsoak to the intake, even with a FMIC.
But again, it all comes down to the actual numbers. How much heat does the turbo really put out with and without the heatshield? It will be interesting to see the results of their test.

The problem with the stock setup, is that the ECU doesn't know your IC is heatsoaked until it hears knock, which can be too late. All it knows with regard to intake temps is what it sees coming by the MAF and what coolant temp it sees. It definitely safens up the tune as a result of high temps by those two sensors, but a heatsoaked IC is going to cause knock most any time you hit full boost, unless you've been doing it enough to train the ECU to pull timing to avoid the knock, which means it's running like crap.
Moral: A hot IC is trouble.

We have multiple locations for the probes because while it is important to keep the intercooler cool, it also helps when your IM runner stays cooler, or your BCS doesn't get nailed with heat, or your throttle body for that matter.

No worries and good points. Really looking forward to the data. I always cringe when I see people running with no heat shield, especially with a TMIC (looks at Van
).
