I got a check eng code 43 FUEL SUPPLY SYSTEM
and I was wondering what that consists of. my set up is a h22a turbo for the fuel i'm runnig an fmu, aem fuel rail, sfc field boxer controler. what going on rigth now is that every time I give it full throtle is leans out and at the same time my sfc goes into "of" mode instead of delivering more fuel
