93 Octane

It felt good on the first 2 logs but on the last one (and after it) I had cyl 2 and 5 super knock shadow codes… I noticed some timing corrections on cyl 2 and 5 specifically. It was breaking up past 6k rpms :(

Forged internals, FBO, GTX2867R .63 A/R, 93 Octane.

So I finally changed my spark plugs, I put brand new NGK 2 step colder ones in and gapped them down to .020 which seems to work well. The car feels clean as far as im concerned, just slightly underwhelming unfortunately :((

Slight misfire run

Any thoughts on my most recent log?
