just pull the efi fuse(under bonnet) out for 20 secs and put it back in, this resets the ecu.

well when the car is fully warmed up the air/fuel ratio should be 14.7 on idle.

when accelerating this will change, depending on if your on/off boost.

cold start = 12.8:1 - 13.5:1

acceleration = 11.6 - 12.3:1

deceleration = 16.2:1 - 17.6:1

light acceleration = 13.7:1 - 15.2:1

hope that helps
