Default AFR dropping?
Not sure what happened, but my AFR has dropped when i'm on full throttle. My AFR on full throttle used to be at 12.9-13.3, but now has dropped to 12.8-10.9 at 6300 RPM. My BPV is also starting to make some swoosh noise that it normally didn't so I don't know if that's the problem or not! Any ideas?

I have the stock airbox in. Could it still be leaking from there? I'll have my exhaust checked out today. Is it dangerous to go full throttle with a leak?

my boost gauge always did that. It was never on a solid number for too long. I'm getting full boost though.

You will still get full boost if you have a leak.
