If my sources and memory are correct:
Peaks vary depending on fuel/ environmental conditions/how hot the turbo is and any intake or exhaust modifications. In this way they also vary from car to car too.
According to Mike Wood from Prodrive, the P1 boost peaks at about 17.5 psi(1.25bar)
It is the held boost the ECU controls and the targets is uses are 15.7 PSI midrange dropping off to 14.6 PSI at the top end. It will never precisely achieve these targets in all gears/conditions/driving situations, but those are the targets in the ECU.
The P1 and STi boost map are both the same, 15.7PSI - dropping to 14.6PSI. These are held boost targets, peaks are higher and variable as said.
