The guage is close but it just doesn't give you the fine detail and doesnt seem to jump up as quick as aftermarket.... but 1 bar means at atmosphere, so 2 bar is ~14.5 psi.

Your numbers aren't bad. 15 psi in 1st gear is a challenge to begin with. You should reach it in 2nd, 3rd etc.....

at what rpm are you reaching boost (15 psi) in the higher gears... 3K, 4K rpm etc.....
