here is a list of your problems ive read so far....

1) your using an s5 engine on an s4 ecu.
2) s5 injectors have diff resistance then s4's (back to #1 problem)
3) compression ratio in s5 engine is diff then s4 (s4=146hp s5=160hp) (back to #1 problem)


solution to try... take s4 injectors and put into s5 engine try that. if that doesnt work then you need to wire it for s5 ecu. or swap back in an s4 engine.
