cobb stg 1 93oc runs rich?

Hey guys, I have gsr with hks filter + t1r testpipe on my gsr.

I'm running cobb stg 1 w. 93 octane, and I notice my af ratio is a bit rich.

At wot, it goes down to 10.5 then leans up till about 11.5

Cobb's map shows that it never goes down 11.3~11.5, and with my testpipe, it should make it a little lean, not rich.

Anybody have same rich ratio?
