I noticed that my AEM boost gauge is reading a few psi off of my data logs, i also noticed there is no option to choose the gm 3bar in the drop down menu, i am currently set to motec 3 bar, I imagine its not good that my ECU sees 2 psi less across the board then what i am actually running, so does any one know the proper scaler and offset for the gm 3 bar part number 12223861? thanks

GM 3 bar map sensor spec
scaler: 628
offset: 0

thanks a million, that confirms the numbers i came up with as well, thanks.
