Hello,

I have a 2010 SHO and it runs great if it has a quarter of a tank or less. Any more than that and it misfires badly. Any clues?

My assumption would be something with the evap system, possibly including the gas cap (if it has one).

Those are fuel pressure codes. You need to verify desired and actual fuel pressures, both high pressure pump and low pressure pump.
