MAP is absolute, and at STP the atmospheric pressure is ~+14.7 psi. This makes the stock 2 bar one measure +/- ~14.7 psi from ambient air pressure. This makes it run out of MAP past ~14.7 psi boost (at STP, less if lower than 0'DA, etc).
Interesting.. I didn't realize the Baro was taken from the MAP sensor. I wonder how they are getting them to read boost past 15psi then. They have a couple guys running 21psi with stock MAP sensors. This would put them 5-6 psi over the readable range of the stock sensor.
