Then on the drive back home, it was back to normal.

Im just curious what could be the cause of this. Is it something I should be concerned about?
Hard to say, but... You can tighten the wastegate actuator on the td04. Look that up on Nasioc with regards to target boost and tuning.

If you're cruising at 5th, and then go WOT without shifting gears, your boost will "creep" as well.
