Hey yall! I’ve got a (near) FBO K24A4 on an element that i just got tuned (ktuner end user) and it feels like it’s pulling way more timing than it was before the tune, which is weird since it was running lean before. The air fuel ratio is spot on and the engine is in good health and i can’t hear any audible knock from it. I’m wondering if it’s a vibration/external noise issue? The car has polyurethane motor mounts, long tube headers, and a bunch of other rattle odds and ends that’s making me think that it’s just “ghost knock”. It also only pulls timing from 2-3k rpm as well and runs 20 deg timing no issue to 7k rpm.
