I'vd done tune up last year,you mention about vacuum leak which remind me of last year when i swapped intake to edelbrock. I removed air pump and all plumming after that the car had idle problem for about the first 2-3 mins everytime after you start the car, found out that there was this little plastic red line in the back of intake that i disconnected when i remove plumming line was unplug.So i plugged it and bamm!! idle was back to normal but then i had a lot of oil inside intake so i plugged vacuum fitting from underneath upper intake which connect to PCV and bypass it to the airbox.I still can hear a small noise of hissing from that fitting but since i do not have any idle problem anymore so i ignor it so the leak may come from there like you said. I will try to have my computer calibrate next
