Have you double checked the map sensor scaling in all of the psi related tables? Correction, Desired psi, and the adder.

Was one of the other 2 tables scaled improperly? The last couple SD 2.0 roms Ive tried had random default scaling in them.

Make sure you change both tabs. You should have a tab that matches your rom and another "base" rom tab.

here are the scalings you will need for the gm 3 bar

Code:

<scaling name="BoostErrorPsi GM3barMAP" units="psi" toexpr="(x-128)/(8*5.728)" frexpr="x*8*5.728+128" format="%.1f" min="-2.8" max="2.8" inc="0.1" storagetype="uint16" endian="big"/>

<scaling name="PSIa16 GM3barMAP" units="PSIa" toexpr="x/(5.728*2)" frexpr="x*(2*5.728)" format="%.1f" min="0" max="29" inc="0.1" storagetype="uint16" endian="big"/>

<scaling name="PSIa8 GM3barMAP" units="PSIa" toexpr="x/(5.728*2)" frexpr="x*(2*5.728)" format="%.1f" min="0" max="30" inc="0.1" storagetype="uint8" endian="big"/>

cheers
