My tune..

Yeah I have 272's. And my car likes it that lean for some reason. I trapped quite a bit higher the more I leaned it out. When I went leaner then 12.5 I wasn't trapping any higher so I left it there. I think I am gonna leave the timing. I talked to the guy who made the chip and I should be at 22 peak timing at 7k. I'll have to check my logger again but I'm pretty sure I was only at 19.

I'd say you could scrounge some more out of it with the almighty Link.
