Could be the IC suffering from heat saturation from boost conditions before WI triggers (13 psi, too high now), once triggered the cooler air now leaving the turbo is being heated by the hotter IC.

Best wait and see what the graph looks like when temps are samples at one or more times per second. Temp spikes could be much higher and vice verser( troughs much lower) At one point 0 degrees Celcius was recorded at the throttle.

What is the ideal inlet temp we are looking for :?:

What is the effect of air temps reaching the cylinders 10 to 15 degrees C less than the ecu thinks :?:
