Well I richened the idle and took the car for a solid drive and seems like both the compression and idle issues are now gone! There is no idle lump but it does not sound like there is any misfiring going on anymore either around 13:1 AFR. I am also assuming that whatever oil was in cylinder 3 burned off finally since my compression test numbers came down and match all the other cylinders now. Thanks for the suggestions, onto tuning and adding boost now!
Just to confirm, while these engines may like rich idles, is there any issues with stoich or even slightly leaner AFRs while cruising?
