I guess I have a way different opinion on cleaning up than you guys do. Not trying to start a fight either so I'm sorry in advance if its coming across that way. What I meant by almost maxing 205's was I had that when I had my 6.0 and at wot once lit, it was smoke free, but had a tiny bit of fuel pulled back and kept egt's at 1550 max. But being a pulling truck if I have read the op's posts right, it doesn't need to be smokeless.
My cr is pulled back a touch and doesn't even haze at wot once lit. And 400's are are an ungodly size, but I have never seen something like that in person.
