Spark plug corrosion

So I had a p0307 go off yesterday and changed all the spark plugs to NGK IX Iridium. Upon removing the spark plugs, I noticed a couple of them had similar corrosion but were different than the others, any idea why?

Kinda looks like that cylinder burns some oil. It's common for the DOD to use some oil.

Ya I was researching the GXP a lot before I bought it and new this was an issue, luckily my car doesn't burn that much right now. I threw a code for a cylinder 7 misfire and wanted to changed all of them because I am not sure how well taken care of it was before I got it. Now it gets the best of everything :th_laugh-lol3: I put some NGK IX in it, and the difference is night and day. Just on the throttle response alone, it moves when you give it some gas. I also put some Fuel System cleaner in my tank when I refilled up so hopefully that'll help freshen everything up. It already has MSD wiring, K&N cold air intake, SLP cat-back exhaust system, transmission cooler, and just slapped some new rubber on her too. In love with this car :th_laugh-lol2:

As far as the spark plug, it looks to me like a combo of just normal where it some of the oil burned, not much, but not the same as the others. It's not something I am worried about though.
 
You're really going to want a tune done asap. Getting that dod crap turned off is a lifesaver for your car. Its also time to invest in oil catch cans .trust me when I tell you its a good investment. LS motors have the most ****ty pcv system to deal with.

I want to get a tune, I was looking at getting the Overkill one but was looking for recommendations. I am somewhat handy with cars, I can do most basic stuff myself, but I am not sure where to even access this chip to get the tune done.
