Different a/f in each gears at same load??

Guys, I've posted a question before asking for some advice on why I'm getting richer and richer a/f as i go up the gears (3-4-5th). Some have recommended me to see if I'm getting higher loads in higher gear, leading to richer a/f from looking at a diff cell on the ecu map.

I've done some logging today and saw that the loads between 3rd 4th 5th are pretty much relatively close to each other but the a/f are still quite different.

I'm attaching a picture of LoadCalc vs. A/F for your reference.

Any advice is much appreciated!!

Leanspool will lean out AFR on the gear you start at WOT. Seach leanspool there are several threads on the topic.

Thanks, but u mean leanspool will lean out the gear I start at? I think a/f of my 3rd gear is OK and don't want to go leaner than 11.7 but I want to richen out 4th and 5th...

not sure if I can disable leanspool for a JDM EVOVII... if not, not sure if adding fuel from 2,500-4,000 would help to eliminate lean spool? thanks
