Angry Possible fuel injector issue?

Put new plugs in about a month ago and started to misfire...swapped coils and still misfiring from time to time in cylinder 5. Weird thing is that it only misfires when I opening her up and when its boosting towards 15lbs...if I keep it to 10lbs its fine. I am going to replaced that plug tomorrow thinking maybe its the plug that is fouled and was bad from the other thought is that if it still does it with the new plug, then it has to be injectors right? Can it be possible that my injector is already bad? I have an 08 with only 50,600 miles on her...just seems strange no misfire when hit around 10, but when you open her up more than that..boom misfire and then it goes away once you turn her off and on again...any thought?
