AF Gauge goes temporarily lean at WOT

[latvianrkey]

I just noticed that when I go WOT, my AF gauge goes extreme lean for a about 1 or 2 seconds and then extreme rich like it normaly does. If I go WOT, the car hesitates for a sec, then the AF gauge reads rich and it takes off like a bat outta hell. All of this started after the install of a MAFT blow-through setup. My idle is set on the MAFT, but the other knobs are all at ZERO. My mods are B16G FMIC with short-route piping, AFC, FP etc. etc. I have not had a chance to log the car yet, but hopefully this weekend I will.

If someone has experienced this b4 let me know what you think.

update: I had the MAFT set at zero accross the board. I set it up for the injector size I have, and it seems to be normal again.
