get a fuel pressure regulator, all it does is create more pressure in the fuel rail which forces more fuel into the engine then just adjust it using a wideband | |

could my drilled airbox be to blame for my car having a flat spot sometimes? | |

I doubt if you are getting more air in, Just better flow and maybe a bit colder, ECU will be able to cope with it fine, Its not like your putting 5psi or more of boost into it. | |

A fuel press reg isn't anything to do with boost, all it does is allow more fuel through to be injected. If you don't up the amount of air entering along with it (ie - through forced induction) all you'll end up doing is overfuelling. | |

Yeah the sensors sort it out as far as the standard ECU will let it because it is limited I think. | |

No, no way of doing it without either just upping the fuel pressure or getting a piggyback ECU | |

It should read the air fuel ratio with the lambda sensor and sort it out on its own. Thats what i always thought anyway. | |

I've done all the standard airbox mods, (drilling, removed plastic pipe in lid, removed vacuum flap mechanism, removed hot air feed). |
