07 Tahoe AFM issue

Post by ACLR8R »

I used the 87 octane tune, and disabled the AFM and noticed some light metallic sounds under light load, almost light detonation. I turned the AFM back on and the sound was gone. Anyone else experience this? You would think it would be the other way around if there was an issue with the AFM. Could it need more octane and actually be detonation? I dont think so because of it disappearing when AFM is active, unless that changes something else.

Any insight would be greatly appreciated! I want to disable it, but dont want to risk damaging the engine.

Thanks
