Codes say the front O2 sensors are not responding to the exhaust stream and fuel adjustments provided by the tune. Could be bad O2's causing the code but as mentioned about this would not be the case on a cold start. You did mention hot start too. What is the difference between hot and cold?
580 sounds a little low for idle setting.
50 running is barely low at all...what pressure does it make on key on while the pump is running without starting the engine.
Also make sure the O2 heater fuses in the underhood fuse block are not blown and all the connections are good.
