    What sled are you running on? Apex I assume? You will have better power at 12.8 on your wideband gauge.

    Yes you will get more top end power by lowering the top end air/fuel ratio.

    As far as I know Schmidt bros only makes the fuel regulator for the Phazer models. I have not tried one, but I am sure the Power Commander would work with it, just would require a different setup on the map.
