normally you only see that on a spark plug that miss fires under load. with the boost you were running it's hard to say if it is normal or not to see the spark through the ceramic. alot of times if i'm chasing a miss that i think is spark related i'll check for this in the dark, but under that kind of cylinder pressure i don't honestly know how it should act.
