When I'm driving I just can't get onto boost. Basic metro turbo engine running a megajolt.

Do you have a wide and connected up? I run a supercharger and I don't care the TB is on the wrong side.

Could be that the fuel pressure is not rising as the boost comes on.

what about the pressure regulator? just thinking aloud but if the diaphragm has spli for instance, it wont be raising the fuel pressure as it comes on boost? |

Pluming looks right. If it was working before then it probably is.

Ignition is megajolt running the default map so should be fine in regards to that |

Plugs are brand new, less than a week old and the signal from the megajolt seems spot on. |

Check that the trigger wheel has not moved. They can slip and will always retard which is lucky. On 26th Oct, 2004 TurboDave16v said:
