need help trouble shooting Options

my 92 laser AWD sputters when i get on the throttle. it doesn't feel like fuel cut beacuse it will keep trying to accelerate. i data logged and my injector duty spikes at 150% and when i do a pull my throttle position is never 100% according to the logger, it jumps between 75 and 95% when my foot is on the floor. timing is steady at 15 degrees and there is no knock. also i keep throwing a CEL for a few seconds when the car is cold. it will go on for a few seconds and then turn off and do that two or three times and then it turns off for good. i tried reading the code with my data logger and there are no stored or currect codes even when the light is still on.

i tried changing my plugs and wires, different 450cc injectors, turning down the boost from 16psi to 11psi, a different MAF, and retuning with my SAFC and nothing has cured my problem. has anyone ever had this problem before. any suggestions would be greatly appreciated. thanks.

i can do pulls to record any other info if it would help. i am using the MMCd logging software.

the only fuel system change that is done to the car is a 3rd gen RX-7 fuel pump and the SAFC (yeah i know i should have got a translator but i got a hellof a deal on the SAFC).
