Default getting fuel cut on turbo crx. why? help?

Hello everyone i have a 91 crx si with a d16y8 thats turboed with a t3 turbo. im using an safc with 450cc injectors and i even have an fmu. it will run rich up to 5200 rpms and then fuel cut will hit. thats only under full throttle. im also using an 89 intergra ecu this happens even lower on the stock si computer. can someone help me. why is it cutting at 5200rpms

i dont think you should be runing an fmu if you have the afc. defeats the purpose of the hack

the ecu is the right one. its out of an 89 integra but it does the same thing with the 91 si ecu tooo. safc is set pretty good. it did the same thing with the fmu and stock injectors
