Looking for heat soak

After reading about what a difference a bigger intercooler makes, I am considering it as my next upgrade. However, I am a little confused on exactly how and when heat soak occurs.

Last night - 90 degree weather, driving home from work and I am getting into full boost on the highway at about 65 mph in 4th gear, going up to 90 or so. I do this repeatedly and it boosts fine each time. If I had heat soak would the boost gauge still go into the red, or would I just experience less pull? I have stock gauges only, I know I need to upgrade those...

Is there differences between the stock 9-3, SE and viggen intercoolers?

How hard do you have to be driving the car to experience heat soak? Does it occur during WOT through multiple gears?

Thanks for any info.
