Put your car in 5th at about 2500rpm. Then, go WOT and watch the boost climb and then settle off. You can try this in 4th if you do not feel comfortable (or have the road room) to do this in 5th or 6th. The higher gears put a higher load on your engine and give you a more prolonged, accurate reading on boost.

At that point, the ECU is able (and has the time) to control the boost. You also see the end-result of other factors that come into play as well (octane rating vs knock - timing retard, air temp, humidity, spark plug quality, any leaks in the air system - BOV quality, etc).
