The only sure way of telling what is what is get it on the rollers where you can see the fuelling under load, someone could well of just whacked the(fuel) rail pressure up via the FPR.
The std 2 bar map sensor will read beyond 2 bar despite it's name, same as the 3 bar will read beyond 3 bar, as each have a over boost reading facility.
The std 2 bar is marked APS 02/03, the 3 bar is marked SPA 05/01.
You may have been very lucky so far, but best get it checked, at the very least a fuelling check, open the ecu and see what the chip has written on it as well.
