Ok next instalment coming up.
I fitted the Maf to my Passat and took it for a blat, seemed much better and of course after spending 300 sovs that's what I wanted to believe.
Trouble is now I'm not so sure, acceleration is still not great and out dragging other cars is a bit of a problem and there's no kick felt when (if?) the turbo kicks in.
It has been suggested that the paramiters on the ECU may need resetting, any thoughts?
