Default Accessport boost psi reading high??

i just got my upgraded accessport and was using it to read the boost levels. In my oem boost gauge, it reads .1mpa max boost. This should equal to 14.5 psi right? But in my accessport, the max boost reads 15.5. Which reading is off?

Also, when the oem boost gauge shows .9 mpa, the accessport shows 14.7. Doesn't this sound wierd? Either the oem boos gauge reads 1-2 psi lower or the accessport is off and reads higher. Any thoughts?

Yeah, I answered this on Cobbs forum for you. Your boost gauge reads low, the reading can vary depending on where you tee off for the gauge line. It doesn't sound weird at all, it sounds pretty normal.
