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

Anyone!?

did you un hook the battery when you switched the pcm? I dont think you should be throwing those codes if the o2's are deleted. But Im sure its something simple.
Bank 1 is the driver side cylinders. That could be that the front o2's are bad, or its really running lean.

Yea I disconnected the battery for sure. Im sure it is either the 0²s or my intake being loose or something Hopefully

when I had an air leak on my intake... it never popped a code... A/F ratio just ran a little lean. Like 13.5

Then it could be something with the MAF ...Damn I hope this turns out to be something minor...

It should nit set those DTC's if the rear O2's were deleted and yes, they're setting because the cats are gone. As far as the lean code, it's kinda rare for one side only to set so look at anything on that bank that could cause a lean condition.

So possibly it might have been a mistake on tuning?

How would I look at the bank? Just check the sensor?

[GasGuzzler]

Look for anything on that side of the engine (bank) that can cause a lean condition. If the rear sensors were deleted in the tune, those DTC's would not set. If you can, look at BOTH banks' long term fuel trim and see if the other side is also on the verge of setting a lean code P0174.

english please...lol jk!

Where and what do I look at?
Do you have a pic I could go by?
