    It is part of the procedure - you don't change anything in the PCM. It will happen if you do the preceeding steps correctly. If done properly, the code will go away.

    The file that downloads from your embedded link above is a tune file, not a log file. I'd bet that your engine is going very lean at 4000 RPM and a log file might reveal that condition.

    My stock 1999 LM7 engine is a steady 18 inches Hg at idle. My vacuum-powered brake booster would be a hunk of useless ballast at 8 inches of mercury.

    A log would help here. My guess is a vacuum leak somewhere and we will see oddball readings for your Long and Short Term Fuel Trims in your log.
