I am looking for advice on how to zero out the baro sensor on my 07 lgt. I believe it's faulty as it is stuck at 21.xx and the map reads 13.xx key on engine off. Rather than purchasing another suction valve just to cut the baro out of it I've been told I can just zero out the table. Thanks!

what rom are you working with?

Can help with this if you have a rom. What value would you like the atmos to read? I set them to 100kpa

The atmospheric pressure sensor was most probably removed with the secondary air system. You rely on that sensor to reduce boost targets at altitude to prevent overspinning the turbo.
