Default CEL & Idle issues after tune

Last night I got a P0420 CEL while driving home. I reset the ecu and reflashed the base map and loaded the real time map. Then when I started the car and drove around I was having issues with the idle and the car would stall in neutral. So I tried reflashing the maps again and then when I started the car I got a P0171 System running lean CEL.

Could there be any mechanical reasons why this is happening? Everything was running just fine up until I reset the ecu that first time.

Sounds like a bad tune?
