Well it was pretty much hovering around a 10.1-10.2 the whole pull. I just went to make a quick pull, not tune it. I still have in the huge corrections from when I had the previous fuel system in it with the fuel pressure dropping. It doesn't exactly drop pressure anymore so it's on the very rich side.
But yes, these plugs do kick *** and seem to be literally unfoulable for an 8 heat range plug.
