600 efi bogs/missfires on full throttle

got my engine back together and have run it for some miles now, and then i wanted to test full throttle. but it bogs or it`s more like that it is missfiring, and it`s a bit smokey (blue) when i hit full throttle. this is a engine, built on a 03 mcat crankcase and crank. with powder 600 efi cylinders, powder injection system (triangel marked), but the ecu is a squered one, with number 3005-391, and the (burned) one from the powder injection system was 3005-392 (triangle).
could this be the ecu`s fault, i that case could i might use the 392 chip in the 391 ecu, if it`s not fried.

ECU and Injectors must match or the sled will not run properly.
The different injectors have different sized orifices and the ECUs are mapped to match.

so, what would be the best to do, could i change the chip in the circel ecu from the old one if it`s not burned that also. or do i need to get the matching injector to the new ecu.

well i got the chip, so i guess i just would try to swap that and see if i got spark then, if not i need the injectors.
