I just bought a 2016 ford focus st. I am already having issues with it. It seems that my ECU can’t match the amount of boost i’m pushing. Very weird noise when I hit boost and my BOV isn’t going off correctly. The car when you let off the gas throws you forward kind of. I am running very rich and i don’t know what to do. The engine code was something about “Turbo boost sensor” “Circuit A” I already replaced both MAP sensors and all the plugs and coils. Im not sure what else i can do and i don’t want to take it to a dealership, if anyone can help please help.
