Arcing sound?

My 03 Lightning makes a weird noise when I get on it. It sounds like electrical arcing but it only does it when under power and at high boost. You can rev it as much as you want in park and it won't do it. So I can't tell what's going on. It's been a few weeks now and it kind of sounds like a loose piece of metal underneath but still I only hear it when I floor it. Any thoughts?
