Sounds like we need a video from @
Nfsundrgrnd with the hood open. I'm not 100% convinced it's DI seals yet, but the knock sound and the low adv. multiplier are certainly concerning.
"quick blips at any rpm" - that's the weird thing about this is that I can rev from 1k to 2,500 or 3,000 over and over and no pop/clunk/knock/whatever. It only does it when it's at the resting ~650rpm idle. Even if I feather slightly to get over the resting idle and then do a throttle stab, no weird noise.
