Injector or cam noise?

Hi there. Video isn’t perfect, but can you help me diagnose whether this is basic injector noise or cam or lifter noise I need to worry about?

From everything I can tell from using a stethoscope, it’s just injector noise — but it sure is loud. I have a BWR supercharger kit and tune, with Bosch injectors from that. Thanks!

The preview plays without sound.. Clicking on the video results in a static image, no video, no sound.

Played fine for me and about the same as my REV 300. Are you referring to the tapping sound? Mines similar.

Cam wiping sounds similar to injector noise but is easy to check. For peace of mind, I'd be quick to pull off the valve cover and look.
