Crazy A/F ratios causing fuel cut like symptom

[DMKDC5]

Car is a 2004 RSX-S
Mods: RBC intake manifold, Hybrid Racing CAI, Ktuned 72mm TB, Megan shorty header, Hondata V4, Hasport mounts.

In the datalog you can see right at 2min 20seconds when I go WOT, the A/F ratios start spiking like crazy and it causes a fuel cut like symptom.
No codes are stored and no MIL comes on. Anyone seen this before? or has any tests I could run to help diag? Thank you in advance.

You are decelerating at 2:20 and it is completely normal for the AF ratio to go full lean at this time.

Sorry, im talking about the spiking in A/F at WOT around 2:25-2:30. I uploaded a screenshot where you can better see what im talking about.

Those are between shifts when you are letting off the throttle.

It is something to do with the way you have remapped the fuel table rpm index and then difference between the low and high speed fuel tables. Look at the fuel injector change at VTEC and how leans it runs at VTEC on the high cam.
