Thanks for this data.
What are your final mods? The manifolds are back on or you have the kooks?

no false knock from the headers? I wonder if that caused the loss with the ARH headers.
NVM I saw your post on hptuners. Let us know how the updated tune the person gave you went.

Just curious, has anybody ran stock cars and manifolds after cam and noticed an odd smell? Not burning oil, not sweet like coolant, more like sulfur and gas? I’m assuming it’s my cats going out but not too sure.

That smell is usually a cat issue. My guess the tuning is incorrect for having cats. Need to keep COT on and command extra fuel when the cats get hot.
