5efhe running lean

did an engine swap in my 92 paseo put in a 5efhe used the stock ecu, wiring harness, injectors, and throttle body. problem is my check engine light is coming with a code 25 which is lean air fuel mixture. i know the o2 is good, changed out the plugs for brand new 88 supercharged mr2 plugs. any ideas what could be causing this? i tried injector cleaner already too. should i just put in the larger injectors that came with the engine?
