I have been fighting an issue on some LML trucks and in pretty much in all operating systems where the turbo desired and actual boost do not follow eachother. Please see the attached log file. It appears that when the truck transfers from Open loop VGT to some other vane control table the turbo vanes actually open up rather than closing down.

I see this has been discussed before but is the resolution that there is a series of tables not mapped out by EFI live that we don't have access too? Similar to the LMM I would expect there to be a turbo vane min and max set of tables. I don't see this being tied to EGR, MAF or a max airflow table, I have logged and not found any correlation.

Thanks for any assistance.
