It would be great if there was a fault code Cass.

My mistake I thought yours was the same P023 fault mine had.

Did you ever get to the bottom of this second one? Mine has a similar lag, I notice the commanded boost never goes above 83% during driving conditions, I have found it revs much quicker on low down rpm with the electric actuators disconnected and held in the 100% position. Does anyone else see 100% commanded boost low down? Cheers. |

I thought I'd figured it out last Tuesday. I fitted a pair of new MAF sensors and it drove great until the weekend when I filled up then back to driving crap.

Fuel tank venting problem or brand of fuel? |

I think it was sainsburys fuel so possibly. Will need to fill up today but its never made a difference it the past.

Focus on port deactivation swirl flaps if they are permamnently closed or vacuum valve is always open so activate it to close 4 ports out of 8 |

Normally flaps are open, closed when activated by vacuum. I disconnected vacuum supply (red) pipe to actuators (blue). Vacuum was present at supply when engine was just started but then later was cut with engine still runing at idle, probably off by valve at front of the engine under vacuum pump near aux belts. Small piece of blue nitrile glove showing vacuum present. Blanked it with other bent hose. You could try to drive with pipe disconnected and blanked.

gruodiz, did you notice any difference when driving with the hose disconnected and blocked? |

Yes, looks like car pulls better. Going to compare on dyno with and without it. |

Been reading through this thread from the beginning. The other common denominator is the driver- maybe an exorcist would help |
