Question: Are you in fact using 1680cc injectors? That equals 160#, which seems to be 100#+ too much. Do you know what the duty cycle is during WOT?
Actually,I have used the injectors of 160 lb, but now Use it 85 lbs ,,because,don't need big injectors it was in idle RPM too much rich
when I used injectors 85lb the duty cycle is 84%
