I know i can adjust the fcd. Its turned all the way clockwise???????

[ep91_glanza]

Anti- clockwise i meant sorry

Fuelling mods are not things to be fiddled with, you need it set up properly using a wideband o2 sensor most likely on a rolling road or you could do some damage.

[ep91_glanza]

Do you reckon i should take the fcd off and run .8 ??

[WallaceGlanza]

Yup, then get it setup properly on a rolling road when you can.

how are you increasing the fuel, for the higher level of boost? seems you could do with a uprated pressure regulator. as when i had the safc, im sure it was increase the fuel pressure via a regulator and/or pump, and then use the safc2 to trim the fueling back a little??

i know its prob not the problem, as it seems to be the fcd, but its something for you to look into
