    Ok so a mate tells me as he waits behind me that i may be running a bit rich, now fuel economy on the JDM motor def seems a bit less than the original but haven't worried too much about it, however after he showed me the think black cloud that came out the exhaust from take off from the traffic lights (on an uphill) seems he may be onto something. now to figure this little bugger out, what makes your car run rich?????? my two main guess's are TPS and O2 sensor so i intend to change those buggers out, but is there anything else? could me tuning the timing 10 degrees advanced have anything to do with it?

    You can also alter the fueling by playing with the spring in the AFM, But I am not sure how accurate this is, and I would only do this on a RR.
