I have a lsvtec gsr head with basic bolt on I H E..and i installed rc 440cc saturated injectors ..my ecu is p72 with obd2 - obd1 conversion....so when i drive my car it uas no power seems like it wants to die when i use revat a stop

 

When i rev the engine

 

did you tune it or just add the injectors and expect the ecu to know what to do?
