It has reduced in severity, but still feels like its tapping the rev limiter at about 5700. I don't have an actual scanner, just an aeroforce interceptor gauge.
-Foghorn "You mentioned 14* KR in your first post, that can certainly make the car feel very flat and powerless. The KR you're getting is likely the result of the increased airflow seen by the MAF now you have higher ratio rockers. It'* unlikely your Long Term Fuel Trims (LTFT) are locking in close to zero when in Power Enrichment (PE) mode. The result is lean fuel mixtures, detonation and then Knock Retard (KR)."
So does that mean the computer needs more time at WOT to re-learn how much fuel is needed? I can do that.
That was my initial impression, but then I thought it was springs.....now I don't know. Do the rockers increase the airflow enough that the computer would need a decent amount of time to relearn the fueling?
