Just recently swapped hpfp and injectors and the car started to make this noise only does it at 1200rpm underload. Does not if you rev it at idle or any other time. Car is procharged and never did it before with it. Any ideas what is causing this.

Hard to tell what I'm hearing.. Is it the high pitch ringing sound?

Figured it out from a Facebook member. It was a nose coming from the engine bay that sounded like it was rattling. Figured out it was the prochargers intake filter rubbing the hood.

The ring is the procharger noise lol
