I went to the dealer for the tsb pcm recall the guys said because of my intake my air is un metered wtf does that mean? how can i fix it

exectly what i thought i kept asking him which sensor was giving a bad reading he said its the computer because you have an intake messing with the fuel mixture this sounded like bull to me

he's an ass hat, we have MPA sensor, completely unaffected but alterations to intake, until you boost
Of course its bull, the O2 sensors measure the air/fuel ratio of the exhaust gas and compensate.
The real kicker of the whole deal is that guy worked at an exhust shop before the chevy dealer and totaly screwed up my exhaust. So when i was talking he said hey you usta come in to my old shop and said yea and told him how he f'ed it up so bad. He acted like it was the other people at the shop.
