no it looks like your o2 sensors are shut off. There is an o2 sensor enable/disable switch from the ecu that is used as a ground reference. It should be near the back of the cylinder head its usually an o-ring and is the hego ground wire. Make sure that wire is hooked up to either the head or a good ground. If you can't find that wire then you will have to jump the ecu wire off at the ecu connector to enable the hegos.
its not wise to go WOT until you have your fuel dialed in
