91 Octane

Same fuel as v3 pulls

BM3

see the video of the odd high pitched noise here, https://photos.app.goo.gl/F5cdWwwM1syvTqPm6 seems like the problem lays with injector 2, no plugs were wet when I pulled them on cold start. inj 1 and 2 were not fully seated, so that was quickly fixed. Any potential for damage to the sealing rings in there?

Bad plugs
