fco = fuel cut off. its when the ecu kills kills ignition to protect the motor. i cant explain any better at the moment, maybe someone else can explain it a little better. basicly its when the motor reaches the peak of the fuel system and cant match the amount of air coming in, so it kills ignition to protect the motor. a mbc will likely make you hit fco, so just turn it down till you dont hit it. if you feel like turning up the boost more you will need to look into getting rid or around fuel cut
