What the ECU sees it actually lower than expected boost levels normally. Since the MAP signal is controlled, the ECU does not see the higher actual values.

That is unless an elf climbs out of the ECU form time to time, installs an Ashcroft gauge and wites down readings for later analysis.

The concerns is any adaptation values getting outside of what would be considered normal.
