Manual L67 tuning advice/help

[0081(2)]

I have read them a few times but still need to go back now and then just to try and understand a few things but most is related for 12p. I'm not too sure if some of the info translates over to the maf stuff and some names are a bit different which throws me now and then.

Thanks for the help, had a loom back through the logs and some might be lean and some not im going to remove spark and add some fuel and go from there.
