Don't forget that if you've got ported bits your boost may drop relative to others.

theres a big difference from 9psi to 0.9 bar - 1 bar is 16psi.

You see about 0.2 bar difference with a ported charger

Normally 1 bar is seen as the pressure of the earths atmosphere at sea level, which is 14.7 psi, but 1 bar actually equates to 14.5psi.

Justin - you're confusing bar with atmospheres. Bar is an SI unit, so its definition doesn't change, atmospheric pressure at sea level is about 1013mBar.

Yes, and 1atm is 14.7psi - which is why people think 1 bar is 14.7psi - because 1bar usually is just accepted as the pressure of the atmosphere. hence the misconception.
