Funny how the Trailing seems like it's burning fine... the Leading, oh boy... look at the carbon buildup...
Any suggestions, besides to lean it out !? Have addetives worked, as I'm about another 3 weeks away from tuning, and that's after about 2-3 weeks of use/abuse...

Actually the trailing doesn't lok so hot either. You are sending too much fuel in cruise condition. I have an AEM as well and 850/1600, my plugs are a creamy coffee color.
The fact that your leading plug (which is the only one firing at low rpms) is worse than the trailing confirms there is too much fuel at low rpms (possibly too much oil injected as well, if you are still using the OMP).

I've been seeing a lot of Blue smoke while standing @ read lights for 2-3 lights to get through... (LA Traffic 
) I was wondering if you could post a screenshot of your OMP /Stepper Motor setup, or post your map in the AEM Section ??
I'm certain something's wrong with the OMP... I tried datalogging the AFR's at idle.. I'm getting 11.8 -> 12.2 roughly.... that should be fine.... maybe a bit rich but if so only by .4 -> .8 afr....

I idle at 12.9-13.4 and cruise between 13.8 to 14.5 afr.
Note: My OMP output is calibrated based on 850 primaries and 1600 secondaries (more fuel, more oil injection).

Thanks, due to my smoking problem My map looks almost inverted, where at 0-The First row over I have 0 % Duty Cycle, to try and keep it for over oiling @ idle, but I'm thinking it might just be oozing out instead of meetering it... or something I'll have to compare my map... Thanks !
