LEAN afr

I just got my car off the dynojet, and I have a problem. We had to abort my first run due to a very lean condition @ wot. (14.7) The tuner at the shop got it down to 12.5, but he had to take his laptop to a 10 to get that. Everyone at the shop seemed to think the top end of my engine is carboned up, and that is what's causing this. Does this sound right? Any other ideas?

Thanks...

COT enabled will make you rich. If you have cats leave COt enabled.

My car has 56k and the 'top end' is clean as a whistle. I doubt that would be the cause. I'm betting all it needs is a good tune, rather than trying to tune by changing commanded afr. There are a lot of stickies at the top of the page than can assist.

Edit: if anything is dirty and needs cleaning, i'm putting my money on the maf. Does the car have a K&N
