Hey guys im throwing a cel,po172 fuel system to rich.I using a vortech fmu 12:1, everything else is stock,fuel pump etc....what can i do to solve this issue?,And the cel comes on sometimes and sometimes it doesnt.And this is my first time ive turboed a car.Thanks in advance.

 

your suppose to run a high pressure fuel pump with the fmu because its is not getting enought pressure. thats your problem your fuel pump is probaly messed up.

 

so i have to upgrade the fuel pump? i have a walbro 255 just not installed yet.
