massive reconfiguration time again.

So assuming your A/F gage is correct, Optimum on a dyno (or in your garage) would be about 13.0, because it should fatten up under load to about a 12.7. This would be where you'd want it on the street in my opinion. And I'd run 12.7 with a little hotter plug, like I mentioned in the above post.

And that's kind of where I used to be at wise and had really rich plugs and thought I smelled fuel in the oil and stuff like that? I was kind of under the impression a perfect burn would be 14.7 at idle, 12.5 at wot, and about 13.8 at Cruze? I agree, maybe I'll try some smaller rods..
