Here are a couple pics of what my plugs look like with the Direct Port setup on the 200 shot. On these pics we had a few too many degrees of timing. But the fuel ring and heat is very happy.. Here is a link for a good read on plugs. Also on this page there are some more good links at the bottom.
Spark Plug Reading 101 by Mike Canter
its amazing what those little 4bangers that are boosted run at. i seen a tegra make its best power at 13.8 thats crazy lean but it liked it and has been there for over a year now.
most import guys here with big boost setups like mid 12s for boost which is crazy as well.
Allen pretty much sum'd it up. Youll gain power leaning it out however to some ppl every single ounce of power isnt worth it to most and is a liability [depending on owner]
old saying tho is lean is mean and on ragged edge is strongest but youre also sitting on that edge
as for AFR for N20 read plugs, to rich on n20 will cause that motor to die faster then you will believe. 12.2 is good starting point for juice

it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference
16's for cruising and 12.5 on spray is no problem. all in timing and fueling.

The best way to ensure your engine survives is to:
Leave it 100% stock, hahahah.

Nitrous and boosted apps are good from 10.5:1 to 12.0:1 @ WOT & reduced timing is recommended. Anywhere in between that a/f is acceptable. Feel free to correct me if I'm wrong.
youre wrong. if you run spray anywhere in that region yoru just asking for a hurt motor. 12.1-12.5 good range but plugs tell the true story
ive sprayed at 13.3 before, picked up a S--t load of mph on a 75 shot
