The overboost feature, when triggered, will induce an extra 1psi of boost for 1.5 seconds. If the regular boost target is 15 (which it is between 5250-6000rpm), it is possible to see 16psi. But it's pretty rare for overboost to be triggered at that RPM due to the underlying logic. But if you routinely see 16psi for sustained periods of time (over 0.5 sec) then you will need to drop the user TQ values a few 5 in that rpm range.
