I should also mention that you should remember to disable (completely) the DSC when dynoing.
3 drive cycles is more than enough to relearn ft.
As for cleaning the maf, if you know what you are doing, you should be fine, but if you did screw something up, I dont think it would throw a misfire code.
As for plugs, I dont see the having incorrect heats being part of a misfire issue. But you should use (or at least read up on) the standard heats for NA and one step colder on leading and trailing for turbo.

Check that the screws are tightening down (not stripped)
