    Not that i don't believe you but I've always been taught in school it was 14.7. I'd think they'd round it to 14.5 if your research was correct. Anyways, close enough!

    im confused, so if my car hits 1.8BAR boost, that cant possibly mean with no mods other than a chip it can be hitting over 15psi?

    that is relative to atmospheric pressure... notice your boost guage sits pretty at 0 when the car is off...
