your turbo is putting in too much air into the cylinders, because its spooling and building too much boost |

bigger injectors and maybe a piggyback, and a upgraded fuel pump, how did this all happen with the turbo? did you just decide to toss in a new turbo? the MAF sensor is reading too much air coming in. the turbo may not be boosting so high but its building up a lot more air than stock since it is a 16g |

ya i'd suggest getting a piggyback too so its its not just dumping air and fuel just cause your parts are making it, you need something to control the mixture you get me? |

unless you have the fuel system to support that 16g run it at stock boost pressure. from the "j" pipe to wastegate actuator.a piggyback is like a SAFC , but preferably get ecmlink bigger injectors and fuel pump and get the car tuned. |

an MBC would be your best route, get one from RRE they can tell you lots about what you need to know |

Make sure youre using the correct plugs. When I first bought my old gst, I had what I thought was fuel cut. I experienced the same symptoms youre describing. After I did the maintenance on it, I found it had the wrong spark plugs and then I put ngk bpr6es plugs and it started boosting fine. I also had an evo3 but it was mated to a 14b on the hotside. I ran it at stock boost and had no problems whatsoever. |
