rb25det neo s13 sputter/hesitation

[Mzag]

hey guys, i know there are a ton of threads about rb25 sputter issues but non have helped me solve my problem. Heres what its doing, under light acceleration, anything below 1/2 throttle, it feels normal other than running really rich(high 9s low 10s). As soon as I go wot, doesnt matter what rpm im at, it will clime maybe 1-2k rpm and then just cut out. Not exactly sure how to describe it but its an abrupt stop, rpm will drop, goes full lean like Im letting off the throttle. Maybe a maf cut? Fuel cut? Heres what I have:
rb25det neo
stock ecu
stock turbo
3" turbo back exhaust
fmic
greddy knock off intake mani
stock coilpacks, ngk bcpr6es plugs

I have already swapped the maf, coilpacks with liquid electrical tape, gapped the plugs smaller, set timing at 15 degrees at 650rpm, set tps to .5v closed, I have not got around to doing a boost leak test but im almost sure there arent any.

Anyways, im at a complete loss with this issue, any advice is greatly appreciated.
