Yea. I think most people tune for mid-11's worst-case. You're at around 13:0 at the top of the rev range.

So to safely get my car where it should to be I want to add some fuel in the WOT map to get that A/F a little lower. I was thinking around the mid 11's would be better...
What about some smoothing? Can I do something to make this easier to read?

How does you timing and knock look at those AFR's? I have run at 12:1 with out knock on 91 but went back to mid 11's based on advice from here.

Well I got the black box version so I cannot see knock unless I want to get a tactrix cable or upgrade my box. I could pull a chart of the timing too.

thats pretty high, with alcohol you should be at least 12.5 the highest and u dont even have that. i would definatly add some fuel for WOT and post your timming. at that high you might be getting some knock i would think

was this during WOT?? if so, then why is your boost readings so low. from what i can tell from your timing table, your ecu is not pulling timing, therefore, your not getting major (5+) knock counts. plus, the timing degree numbers seem good and progressivley increasing. finally, your IDC is no where near 100%, so your not maxing out your injectors. with cams, you will usually see 95+% IDC at high rpms.

Well I know I am having boost issues. I am going to convert to hard piping and probably a different MBC to be sure.

Not pulling timing? Are you looking at the same timing curve I am?
You AFR is way way way too lean. Get it in the 11's and see if your timing curve stops having all those dips in it, which is pulled timing. It should progress like a stair case as your RPM goes up, like this:
