Right plug looks like that cylinder ran lean. I'm ahocked that you can run 31 psi on 92! On 91, I'd be worried hitting 25 psi.

 

Like super bad lean or just tad bit?

Yeah it was a glory run, backed it down, kind of want to run 27~ on 92

Going to e85 soon, not sure how a dual map works with a MBC though

 

Super lean wouldn't be white. It'd be missing the tip.
Is that your #4 cylinder?
What was AFR on that pull?

 

I think it was #1 actually
Like high 11s in the upper RPMS
I ran out of octane probably
ID1000s in there with a 255

Just got 1650 FIC low z and new 450 wally

btw plugs were BEFORE the tune, I havent checked the new ones since

 

why do you say that? do you even know how to read plugs?
the photo shown is not enough info to read them.
you need to cut the threads off and read the porcelain, or at the very least look down into the plug. --> http://www.jetsrus.com/photos/photo_...g_reading2.JPG
so much terrible info on this board, its unfortunate.

 

You're right, on my phone, tip looks white. But I can't be sure how true the color is on my screen. I guess I should put a disclaimer on all my comments and bold looks

 

My intent was to warn him to be careful to protect his engine. Maybe I should stay quiet and wait until he blows his engine and then lecture him?
