what is this noise?

I was running JB4 map 1 with intake/exhaust and I had it throw misfire cylinder 3. A few days later this noise appears. I have the engine cover and cowl off so you can hear the noise better. Not sure if this is the infamous waste gate rattle or not, it seems like its coming from inside the motor but I can't be certain. What do you think??

The clacking noise you are hearing when it idles down is the injectors.This is a normal noise from Direct Injection injectors. That is not a wastegate rattle.
