Help Needed! 4 Codes after Retune

[C-WAY]

Well I went to autozone earlier to figure out what the deal was with the check engine light still being on. I figured maybe it was the radio harness due to the fact I dont have the updated one but it wasnt. They scanned it and returned me these 4 codes:

P0420 - Catalyst efficiency low-bank 1
P0430 - Catalyst efficiency low-bank 2

(Im assuming those are from having no cats, but I thought Allen deleted the Cats off my PCM?) Am I suppost to unhook the 0² Sensors so it does not throw codes?

Then the other 2 are:

P0171 - Fuel Trim bank one condition

They said the fuel system for cylinder #1 was running too lean or something?

P0106 - MAF sensor condition (said the PCM has noticed the input from the manifold absolute pressure sensor or barometric pressure sensor has changed too much) (Could this be from the retune or my intake tube being loose or off?)

Any knowledge to this problem and all help is appreciated!

-----> ALLEN OR MELISSA! Are yall open on wedensday? If so could I swing by the shop and see if allen could fix this problem? I could also bring my extra PCM by that way I wont have to mail it
