Great, some real data! Contrary to what you may think I am actually genuinely interested in how well the WAIC setups work.
So if we look at the longest on boost segment, 460 - 500seconds, IAT goes from about 30C to 60C in 40seconds.
Comparably, the FMIC setup goes from 30C to 45C after 8 minutes
NB, your ECT is getting worryingly high after that on boost period, could the intercooler radiator be blocking flow to the coolant radiator?
More analysis on the cool down time needed I think, i'll have a dig through my datalogs to find some comparable data
