when you do a compression the guage has a check valve in it so pressure wont bleed of untill you push the button you should do a leak down test just because your engine shows good compression dosent mean it will pass a leak down test and you could have just had a plug go dead

i bet your spark plug backed out a little bit. I've had this happen to me on another car, and it caused missing and went rich.

here is a good website for reading your spark plugs.

NGK Spark Plugs USA

It appears to me that your plugs are dry fouled. Sounds like you should consult your tuner.
