please excuse my laziness with the c&p-ing.
Like Marc says, you need to adjust it. He gave you the correct formula.
To find out if there is a problem you need to compare requested boost pressure to actual boost pressure. It is the deviation between these two values that would indicate problems. If there is only minimal deviation, then that means your chip is only asking for 14 psi.
I know GIAC chips peak to 16 or 17 psi, but only hold at 14 or 15 psi.

Marc says that I'm supposed to adjust for the ambient pressure with the formula (mBar-1000)/1000*14.50377.... is this true? It would then bring me down to about 14psi which is low. When logging I used the advanced measuring blocks and "boost pressure - (actual)", so does that not automatically adjust for the pressure?
The torque peaked at about 350Nm on some pulls.
also, mods are just a chip(apr).
