2006 Supercharged Possible Vacuum Leak?

2006 Supercharged Possible Vacuum Leak?
Hi. I have a 2006 Range Rover with the 4.2-liter supercharged engine, which I acquired as a project car
I've had a persistent CEL and when I pulled the codes, it said that both banks were running too lean. That makes sense, because the RR stalls immediately after a cold start, has a rough idle, and surges. I opened the hood and can hear hissing very close to the left side of the engine, near the PCV valve under the engine cover. I have replaced the PCV valve, but it was hissing before that. Since the hissing is significant enough for me to hear it, I'm hoping I can avoid a smoke test and solve it myself. It appears to be a rather large vacuum leak.
Before I take the engine cover back off, does anyone know which components/hoses in that area could be causing the hissing/vacuum leak? (Picture attached for reference)

Same thing on my 06 standard HSE
